Write Styler to an Excel sheet.
To write a single Styler to an Excel .xlsx file it is only necessary to
specify a target file name. To write to multiple sheets it is necessary to
create an ExcelWriter object with a target file name, and specify a sheet
in the file to write to.
Multiple sheets may be written to by specifying unique sheet_name.
With all data written to the file it is necessary to save the changes.
Note that creating an ExcelWriter object with a file name that already
exists will result in the contents of the existing file being erased.
File path or existing ExcelWriter.
Name of sheet which will contain DataFrame.
Missing data representation.
Format string for floating point numbers. For example
float_format="%.2f" will format 0.1234 to 0.12.
Columns to write.
Write out the column names. If a list of string is given it is
assumed to be aliases for the column names.
Write row names (index).
Column label for index column(s) if desired. If not specified, and
header and index are True, then the index names are used. A
sequence should be given if the DataFrame uses MultiIndex.
Upper left cell row to dump data frame.
Upper left cell column to dump data frame.
Write engine to use, ‘openpyxl’ or ‘xlsxwriter’. You can also set this
via the options io.excel.xlsx.writer, io.excel.xls.writer, and
Deprecated since version 1.2.0: As the xlwt package is no longer
maintained, the xlwt engine will be removed in a future version
Write MultiIndex and Hierarchical Rows as merged cells.
Encoding of the resulting excel file. Only necessary for xlwt,
other writers support unicode natively.
Representation for infinity (there is no native representation for
infinity in Excel).
Display more information in the error logs.
Specifies the one-based bottommost row and rightmost column that
is to be frozen.
Extra options that make sense for a particular storage connection, e.g.
host, port, username, password, etc., if using a URL that will
be parsed by fsspec, e.g., starting “s3://”, “gcs://”. An error
will be raised if providing this argument with a non-fsspec URL.
See the fsspec and backend storage implementation docs for the set of
allowed keys and values.
New in version 1.2.0.
Write DataFrame to a comma-separated values (csv) file.
Class for writing DataFrame objects into excel sheets.
Read an Excel file into a pandas DataFrame.
Read a comma-separated values (csv) file into DataFrame.
For compatibility with to_csv(),
to_excel serializes lists and dicts to strings before writing.
Once a workbook has been saved it is not possible write further data
without rewriting the whole workbook.
Create, write to and save a workbook:
>>> df1 = pd.DataFrame([['a', 'b'], ['c', 'd']],
... index=['row 1', 'row 2'],
... columns=['col 1', 'col 2'])
To specify the sheet name:
If you wish to write to more than one sheet in the workbook, it is
necessary to specify an ExcelWriter object:
>>> df2 = df1.copy()
>>> with pd.ExcelWriter('output.xlsx') as writer:
... df1.to_excel(writer, sheet_name='Sheet_name_1')
... df2.to_excel(writer, sheet_name='Sheet_name_2')
ExcelWriter can also be used to append to an existing Excel file:
>>> with pd.ExcelWriter('output.xlsx',
... mode='a') as writer:
... df.to_excel(writer, sheet_name='Sheet_name_3')
To set the library that is used to write the Excel file,
you can pass the engine keyword (the default engine is
automatically chosen depending on the file extension):
>>> df1.to_excel('output1.xlsx', engine='xlsxwriter')
