A local file could be: ``file://localhost/path/to/table.xlsx``. + + If you want to pass in a path object, pandas accepts any ``os.PathLike``. + + By file-like object, we refer to objects with a ``read()`` method, + such as a file handle (e.g. via builtin ``open`` function) + or ``StringIO``. + + sheet_name : str, int, list, or None, default 0 + Strings are used for sheet names.

If a list of integers is passed those row positions will + be combined into a ``MultiIndex``. Use None if there is no header. + names : array-like, default None + List of column names to use. If file contains no header row, + then you should explicitly pass header=None. + index_col : int, str, list of int, default None + Column (0-indexed) to use as the row labels of the DataFrame. + Pass None if there is no such column. If a list is passed, + those columns will be combined into a ``MultiIndex``. If a + subset of data is selected with ``usecols``, index_col + is based on the subset. + + Missing values will be forward filled to allow roundtripping with + ``to_excel`` for ``merged_cells=True``. To avoid forward filling the + missing values use ``set_index`` after reading the data instead of + ``index_col``. + usecols : str, list-like, or callable, default None + * If None, then parse all columns. + * If str, then indicates comma separated list of Excel column letters + and column ranges (e.g. "A:E" or "A,C,E:F").

E.g. {'a': np.float64, 'b': np.int32} + Use ``object`` to preserve data as stored in Excel and not interpret dtype, + which will necessarily result in ``object`` dtype. + If converters are specified, they will be applied INSTEAD + of dtype conversion. + If you use ``None``, it will infer the dtype of each column based on the data. + engine : {'openpyxl', 'calamine', 'odf', 'pyxlsb', 'xlrd'}, default None + If io is not a buffer or path, this must be set to identify io. + Engine compatibility : + + - ``openpyxl`` supports newer Excel file formats. + - ``calamine`` supports Excel (.xls, .xlsx, .xlsm, .xlsb) + and OpenDocument (.ods) file formats. + - ``odf`` supports OpenDocument file formats (.odf, .ods, .odt). + - ``pyxlsb`` supports Binary Excel files. + - ``xlrd`` supports old-style Excel files (.xls). + + When ``engine=None``, the following logic will be used to determine the engine: + + - If ``path_or_buffer`` is an OpenDocument format (.odf, .ods, .odt), + then `odf `_ will be used. + - Otherwise if ``path_or_buffer`` is an xls format, ``xlrd`` will be used. + - Otherwise if ``path_or_buffer`` is in xlsb format, ``pyxlsb`` will be used. + - Otherwise ``openpyxl`` will be used. + + converters : dict, default None + Dict of functions for converting values in certain columns. Keys can + either be integers or column labels, values are functions that take one + input argument, the Excel cell content, and return the transformed + content. + true_values : list, default None + Values to consider as True. + false_values : list, default None + Values to consider as False. + skiprows : list-like, int, or callable, optional + Line numbers to skip (0-indexed) or number of lines to skip (int) at the + start of the file. If callable, the callable function will be evaluated + against the row indices, returning True if the row should be skipped and + False otherwise.

Does not include header rows. + na_values : scalar, str, list-like, or dict, default None + Additional strings to recognize as NA/NaN. If dict passed, specific + per-column NA values.

In + data without any NAs, passing ``na_filter=False`` can improve the + performance of reading a large file. + verbose : bool, default False + Indicate number of NA values placed in non-numeric columns. + parse_dates : bool, list-like, or dict, default False + The behavior is as follows: + + * ``bool``. If True -> try parsing the index. + * ``list`` of int or names. e.g. If [1, 2, 3] -> try parsing columns 1, 2, 3 + each as a separate date column. + * ``list`` of lists. e.g. If [[1, 3]] -> combine columns 1 and 3 and parse as + a single date column. + * ``dict``, e.g. {'foo' : [1, 3]} -> parse columns 1, 3 as date and call + result 'foo' + + If a column or index contains an unparsable date, the entire column or + index will be returned unaltered as an object data type. If you don`t want to + parse some cells as date just change their type in Excel to "Text". + For non-standard datetime parsing, use ``pd.to_datetime`` after + ``pd.read_excel``. + + Note: A fast-path exists for iso8601-formatted dates. + date_format : str or dict of column -> format, default ``None`` + If used in conjunction with ``parse_dates``, will parse dates according to this + format. For anything more complex, + please read in as ``object`` and then apply :func:`to_datetime` as-needed. + + .. versionadded:: 2.0.0 + + thousands : str, default None + Thousands separator for parsing string columns to numeric. Note that + this parameter is only necessary for columns stored as TEXT in Excel, + any numeric columns will automatically be parsed, regardless of display + format. + decimal : str, default '.' + Character to recognize as decimal point for parsing string columns to numeric. + Note that this parameter is only necessary for columns stored as TEXT in Excel, + any numeric columns will automatically be parsed, regardless of display + format.(e.g. use ',' for European data). + comment : str, default None + Comments out remainder of line. Pass a character or characters to this + argument to indicate comments in the input file. Any data between the + comment string and the end of the current line is ignored. + skipfooter : int, default 0 + Rows at the end to skip (0-indexed). + storage_options : dict, optional + Extra options that make sense for a particular storage connection, e.g. + host, port, username, password, etc. For HTTP(S) URLs the key-value pairs + are forwarded to ``urllib.request.Request`` as header options.

A local file could be: file://localhost/path/to/table.csv. + + If you want to pass in a path object, pandas accepts any ``os.PathLike``. + + By file-like object, we refer to objects with a ``read()`` method, such as + a file handle (e.g. via builtin ``open`` function) or ``StringIO``. + sep : str, default ',' + Character or regex pattern to treat as the delimiter. If ``sep=None``, the + C engine cannot automatically detect + the separator, but the Python parsing engine can, meaning the latter will + be used and automatically detect the separator from only the first valid + row of the file by Python's builtin sniffer tool, ``csv.Sniffer``. + In addition, separators longer than 1 character and different from + ``'\\s+'`` will be interpreted as regular expressions and will also force + the use of the Python parsing engine. Note that regex delimiters are prone + to ignoring quoted data. Regex example: ``'\\r\\t'``. + delimiter : str, optional + Alias for ``sep``. + header : int, Sequence of int, 'infer' or None, default 'infer' + Row number(s) containing column labels and marking the start of the + data (zero-indexed). Default behavior is to infer the column names: + if no ``names`` + are passed the behavior is identical to ``header=0`` and column + names are inferred from the first line of the file, if column + names are passed explicitly to ``names`` then the behavior is identical to + ``header=None``. Explicitly pass ``header=0`` to be able to + replace existing names. The header can be a list of integers that + specify row locations for a :class:`~pandas.MultiIndex` on the columns + e.g. ``[0, 1, 3]``. Intervening rows that are not specified will be + skipped (e.g. 2 in this example is skipped). Note that this + parameter ignores commented lines and empty lines if + ``skip_blank_lines=True``, so ``header=0`` denotes the first line of + data rather than the first line of the file. + + When inferred from the file contents, headers are kept distinct from + each other by renaming duplicate names with a numeric suffix of the form + ``".{{count}}"`` starting from 1, e.g. ``"foo"`` and ``"foo.1"``. + Empty headers are named ``"Unnamed: {{i}}"`` or `` + "Unnamed: {{i}}_level_{{level}}"`` + in the case of MultiIndex columns. + names : Sequence of Hashable, optional + Sequence of column labels to apply. If the file contains a header row, + then you should explicitly pass ``header=0`` to override the column names. + Duplicates in this list are not allowed. + index_col : Hashable, Sequence of Hashable or False, optional + Column(s) to use as row label(s), denoted either by column labels or column + indices. If a sequence of labels or indices is given, + :class:`~pandas.MultiIndex` + will be formed for the row labels. + + Note: ``index_col=False`` can be used to force pandas to *not* use the first + column as the index, e.g., when you have a malformed file with delimiters at + the end of each line. + usecols : Sequence of Hashable or Callable, optional + Subset of columns to select, denoted either + by column labels or column indices. + If list-like, all elements must either + be positional (i.e. integer indices into the document columns) or strings + that correspond to column names provided either by the user in ``names`` or + inferred from the document header row(s). + If ``names`` are given, the document + header row(s) are not taken into account. For example, a valid list-like + ``usecols`` parameter would be ``[0, 1, 2]`` or ``['foo', 'bar', 'baz']``. + Element order is ignored, so ``usecols=[0, 1]`` is the same as ``[1, 0]``. + To instantiate a :class:`~pandas.DataFrame` from ``data`` with element order + preserved use ``pd.read_csv(data, usecols=['foo', 'bar'])[['foo', 'bar']]`` + for columns in ``['foo', 'bar']`` order or + ``pd.read_csv(data, usecols=['foo', 'bar'])[['bar', 'foo']]`` + for ``['bar', 'foo']`` order. + + If callable, the callable function will be evaluated against the column + names, returning names where the callable function evaluates to ``True``. An + example of a valid callable argument would be ``lambda x: x.upper() in + ['AAA', 'BBB', 'DDD']``. Using this parameter results in much faster + parsing time and lower memory usage. + dtype : dtype or dict of {{Hashable : dtype}}, optional + Data type(s) to apply to either the whole dataset or individual columns. + E.g., ``{{'a': np.float64, 'b': np.int32, 'c': 'Int64'}}`` + Use ``str`` or ``object`` together with suitable ``na_values`` settings + to preserve and not interpret ``dtype``. + If ``converters`` are specified, they will be applied INSTEAD + of ``dtype`` conversion. Specify a ``defaultdict`` as input where + the default determines the ``dtype`` + of the columns which are not explicitly + listed. + engine : {{'c', 'python', 'pyarrow'}}, optional + Parser engine to use.

Useful for reading pieces of large files. + Refers to the number of data rows in the returned DataFrame, excluding: + + * The header row containing column names. + * Rows before the header row, if ``header=1`` or larger. + + Example usage: + + * To read the first 999,999 (non-header) rows: + ``read_csv(..., nrows=999999)`` + + * To read rows 1,000,000 through 1,999,999: + ``read_csv(..., skiprows=1000000, nrows=999999)`` + + na_values : Hashable, Iterable of Hashable or dict of {{Hashable : Iterable}}, + optional + Additional strings to recognize as ``NA``/``NaN``. If ``dict`` + passed, specific + per-column ``NA`` values.

In + data without any ``NA`` values, passing ``na_filter=False`` can improve the + performance of reading a large file. + skip_blank_lines : bool, default True + If ``True``, skip over blank lines rather than interpreting as ``NaN`` values. + parse_dates : bool, None, list of Hashable, default None + The behavior is as follows: + + * ``bool``. If ``True`` -> try parsing the index. + * ``None``. Behaves like ``True`` if ``date_format`` is specified. + * ``list`` of ``int`` or names. + e.g. If ``[1, 2, 3]`` -> try parsing columns 1, 2, 3 + each as a separate date column. + + If a column or index cannot be represented as an array of ``datetime``, + say because of an unparsable value or a mixture of timezones, the column + or index will be returned unaltered as an ``object`` data type. For + non-standard ``datetime`` parsing, use :func:`~pandas.to_datetime` after + :func:`~pandas.read_csv`. + + Note: A fast-path exists for iso8601-formatted dates. + date_format : str or dict of column -> format, optional + Format to use for parsing dates and/or times when + used in conjunction with ``parse_dates``. + The strftime to parse time, e.g. :const:`"%d/%m/%Y"`. See + `strftime documentation + `_ for more information on choices, though + note that :const:`"%f"`` will parse all the way up to nanoseconds. + You can also pass: + + - "ISO8601", to parse any `ISO8601 `_ + time string (not necessarily in exactly the same format); + - "mixed", to infer the format for each element individually. This is risky, + and you should probably use it along with `dayfirst`. + + .. versionadded:: 2.0.0 + dayfirst : bool, default False + DD/MM format dates, international and European format. + cache_dates : bool, default True + If ``True``, use a cache of unique, converted dates to apply the ``datetime`` + conversion.

Quoted + items can include the ``delimiter`` and it will be ignored. + quoting : {{0 or csv.QUOTE_MINIMAL, 1 or csv.QUOTE_ALL, + 2 or csv.QUOTE_NONNUMERIC, 3 or csv.QUOTE_NONE}}, default csv.QUOTE_MINIMAL + Control field quoting behavior per ``csv.QUOTE_*`` constants. Default is + ``csv.QUOTE_MINIMAL`` (i.e., 0) which implies that + only fields containing special + characters are quoted (e.g., characters defined + in ``quotechar``, ``delimiter``, + or ``lineterminator``. + doublequote : bool, default True + When ``quotechar`` is specified and ``quoting`` is not ``QUOTE_NONE``, indicate + whether or not to interpret two consecutive ``quotechar`` elements INSIDE a + field as a single ``quotechar`` element. + escapechar : str (length 1), optional + Character used to escape other characters. + comment : str (length 1), optional + Character indicating that the remainder of line should not be parsed. + If found at the beginning + of a line, the line will be ignored altogether. This parameter must be a + single character. Like empty lines (as long as ``skip_blank_lines=True``), + fully commented lines are ignored by the parameter ``header`` but not by + ``skiprows``. For example, if ``comment='#'``, parsing + ``#empty\\na,b,c\\n1,2,3`` with ``header=0`` will result in ``'a,b,c'`` being + treated as the header. + encoding : str, optional, default 'utf-8' + Encoding to use for UTF when reading/writing (ex. ``'utf-8'``). `List of Python + standard encodings + `_ . + + encoding_errors : str, optional, default 'strict' + How encoding errors are treated. `List of possible values + `_ . + + dialect : str or csv.Dialect, optional + If provided, this parameter will override values (default or not) for the + following parameters: ``delimiter``, ``doublequote``, ``escapechar``, + ``skipinitialspace``, ``quotechar``, and ``quoting``.

Default behavior + is to infer the column names: if no ``names`` + are passed the behavior is identical to ``header=0`` and column + names are inferred from the first line of the file, if column + names are passed explicitly to ``names`` then the behavior is identical to + ``header=None``. Explicitly pass ``header=0`` to be able to + replace existing names. The header can be a list of integers that + specify row locations for a :class:`~pandas.MultiIndex` on the columns + e.g. ``[0, 1, 3]``. Intervening rows that are not specified will be + skipped (e.g. 2 in this example is skipped). Note that this + parameter ignores commented lines and empty lines if + ``skip_blank_lines=True``, so ``header=0`` denotes the first line of + data rather than the first line of the file. + + When inferred from the file contents, headers are kept distinct from + each other by renaming duplicate names with a numeric suffix of the form + ``".{{count}}"`` starting from 1, e.g. ``"foo"`` and ``"foo.1"``. + Empty headers are named + ``"Unnamed: {{i}}"`` or ``"Unnamed: {{i}}_level_{{level}}"`` + in the case of MultiIndex columns. + names : Sequence of Hashable, optional + Sequence of column labels to apply.

If a sequence of labels or indices is given, + :class:`~pandas.MultiIndex` + will be formed for the row labels. + + Note: ``index_col=False`` can be used to force pandas to *not* use the first + column as the index, e.g., when you have a malformed file with delimiters at + the end of each line. + usecols : Sequence of Hashable or Callable, optional + Subset of columns to select, denoted either by column labels or column indices. + If list-like, all elements must either + be positional (i.e. integer indices into the document columns) or strings + that correspond to column names provided either by the user in ``names`` or + inferred from the document header row(s). If ``names`` are given, the document + header row(s) are not taken into account. For example, a valid list-like + ``usecols`` parameter would be ``[0, 1, 2]`` or ``['foo', 'bar', 'baz']``. + Element order is ignored, so ``usecols=[0, 1]`` is the same as ``[1, 0]``. + To instantiate a :class:`~pandas.DataFrame` from ``data`` with element order + preserved use ``pd.read_csv(data, usecols=['foo', 'bar'])[['foo', 'bar']]`` + for columns in ``['foo', 'bar']`` order or + ``pd.read_csv(data, usecols=['foo', 'bar'])[['bar', 'foo']]`` + for ``['bar', 'foo']`` order. + + If callable, the callable function will be evaluated against the column + names, returning names where the callable function evaluates to ``True``. An + example of a valid callable argument would be ``lambda x: x.upper() in + ['AAA', 'BBB', 'DDD']``.

Useful for reading pieces of large files. + Refers to the number of data rows in the returned DataFrame, excluding: + + * The header row containing column names. + * Rows before the header row, if ``header=1`` or larger. + + Example usage: + + * To read the first 999,999 (non-header) rows: + ``read_csv(..., nrows=999999)`` + + * To read rows 1,000,000 through 1,999,999: + ``read_csv(..., skiprows=1000000, nrows=999999)`` + + na_values : Hashable, Iterable of Hashable or dict of {{Hashable : Iterable}}, + optional + Additional strings to recognize as ``NA``/``NaN``. + If ``dict`` passed, specific + per-column ``NA`` values. By default the following values are interpreted as + ``NaN``: empty string, "NaN", "N/A", "NULL", and other + common representations of missing data. + keep_default_na : bool, default True + Whether or not to include the default ``NaN`` values when parsing the data. + Depending on whether ``na_values`` is passed in, the behavior is as follows: + + * If ``keep_default_na`` is ``True``, + and ``na_values`` are specified, ``na_values`` + is appended to the default ``NaN`` values used for parsing. + * If ``keep_default_na`` is ``True``, and ``na_values`` are not specified, only + the default ``NaN`` values are used for parsing. + * If ``keep_default_na`` is ``False``, and ``na_values`` are specified, only + the ``NaN`` values specified ``na_values`` are used for parsing. + * If ``keep_default_na`` is ``False``, and ``na_values`` are not specified, no + strings will be parsed as ``NaN``. + + Note that if ``na_filter`` is passed in as + ``False``, the ``keep_default_na`` and + ``na_values`` parameters will be ignored. + na_filter : bool, default True + Detect missing value markers (empty strings and the value of ``na_values``). In + data without any ``NA`` values, passing ``na_filter=False`` can improve the + performance of reading a large file. + skip_blank_lines : bool, default True + If ``True``, skip over blank lines rather than interpreting as ``NaN`` values. + parse_dates : bool, None, list of Hashable, default None + The behavior is as follows: + + * ``bool``. If ``True`` -> try parsing the index. + * ``None``. Behaves like ``True`` if ``date_format`` is specified. + * ``list`` of ``int`` or names. + e.g. If ``[1, 2, 3]`` -> try parsing columns 1, 2, 3 + each as a separate date column. + + If a column or index cannot be represented as an array of ``datetime``, + say because of an unparsable value or a mixture of timezones, the column + or index will be returned unaltered as an ``object`` data type.
