pandas.io.formats.style.Styler.to_excel

Styler.to_excel(excel_writer, sheet_name='Sheet1', na_rep='', float_format=None, columns=None, header=True, index=True, index_label=None, startrow=0, startcol=0, engine=None, merge_cells=True, encoding=None, inf_rep='inf', verbose=True, freeze_panes=None)

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.

Parameters

excel_writerpath-like, file-like, or ExcelWriter object

File path or existing ExcelWriter.

sheet_namestr, default ‘Sheet1’

Name of sheet which will contain DataFrame.

na_repstr, default ‘’

Missing data representation.

float_formatstr, optional

Format string for floating point numbers. For example float_format="%.2f" will format 0.1234 to 0.12.

columnssequence or list of str, optional

Columns to write.

headerbool or list of str, default True

Write out the column names. If a list of string is given it is assumed to be aliases for the column names.

indexbool, default True

Write row names (index).

index_labelstr or sequence, optional

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.

startrowint, default 0

Upper left cell row to dump data frame.

startcolint, default 0

Upper left cell column to dump data frame.

enginestr, optional

Write engine to use, ‘openpyxl’ or ‘xlsxwriter’. You can also set this via the options io.excel.xlsx.writer, io.excel.xls.writer, and io.excel.xlsm.writer.

Deprecated since version 1.2.0: As the xlwt package is no longer maintained, the xlwt engine will be removed in a future version of pandas.

merge_cellsbool, default True

Write MultiIndex and Hierarchical Rows as merged cells.

encodingstr, optional

Encoding of the resulting excel file. Only necessary for xlwt, other writers support unicode natively.

inf_repstr, default ‘inf’

Representation for infinity (there is no native representation for infinity in Excel).

verbosebool, default True

Display more information in the error logs.

freeze_panestuple of int (length 2), optional

Specifies the one-based bottommost row and rightmost column that is to be frozen.

storage_optionsdict, optional

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.

to_csv

Write DataFrame to a comma-separated values (csv) file.

Class for writing DataFrame objects into excel sheets.

read_excel

Read an Excel file into a pandas DataFrame.

read_csv

Read a comma-separated values (csv) file into DataFrame.

Notes

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.

Examples

Create, write to and save a workbook:

>>> df1 = pd.DataFrame([['a', 'b'], ['c', 'd']],
...                    index=['row 1', 'row 2'],
...                    columns=['col 1', 'col 2'])
>>> df1.to_excel("output.xlsx")  

To specify the sheet name:

>>> df1.to_excel("output.xlsx",
...              sheet_name='Sheet_name_1')  

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')
