Python pandas save to excel

pandas.DataFrame.to_excel#

DataFrame. 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 , inf_rep = ‘inf’ , freeze_panes = None , storage_options = None , engine_kwargs = None ) [source] #

Write object to an Excel sheet.

To write a single object 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_writer path-like, file-like, or ExcelWriter object

File path or existing ExcelWriter.

sheet_name str, default ‘Sheet1’

Name of sheet which will contain DataFrame.

na_rep str, default ‘’

Missing data representation.

float_format str, optional

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

columns sequence or list of str, optional

header bool 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.

index bool, default True

index_label str 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.

startrow int, default 0

Upper left cell row to dump data frame.

startcol int, default 0

Upper left cell column to dump data frame.

engine str, optional

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

merge_cells bool, default True

Write MultiIndex and Hierarchical Rows as merged cells.

inf_rep str, default ‘inf’

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

freeze_panes tuple of int (length 2), optional

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

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. For other URLs (e.g. starting with “s3://”, and “gcs://”) the key-value pairs are forwarded to fsspec.open . Please see fsspec and urllib for more details, and for more examples on storage options refer here.

Arbitrary keyword arguments passed to excel engine.

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.

Add styles to Excel sheet.

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 to 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']) >>> 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: . df1.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')
