to_excel(self, excel_writer, sheet_name: 'str' = 'Sheet1', na_rep: 'str' = '', float_format: 'str | None' = 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, storage_options: 'StorageOptions' = None) -> 'None'
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.
For compatibility with ~DataFrame.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.
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 :None:None:`header` and :None:None:`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 io.excel.xlsm.writer
.
As the :None:None:`xlwt <https://pypi.org/project/xlwt/>` package is no longer maintained, the xlwt
engine will be removed in a future version of pandas.
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. For HTTP(S) URLs the key-value pairs are forwarded to urllib
as header options. For other URLs (e.g. starting with "s3://", and "gcs://") the key-value pairs are forwarded to fsspec
. Please see fsspec
and urllib
for more details.
Write object to an Excel sheet.
ExcelWriter
Class for writing DataFrame objects into excel sheets.
read_csv
Read a comma-separated values (csv) file into DataFrame.
read_excel
Read an Excel file into a pandas DataFrame.
to_csv
Write DataFrame to a comma-separated values (csv) file.
Create, write to and save a workbook:
This example is valid syntax, but we were not able to check execution>>> df1 = pd.DataFrame([['a', 'b'], ['c', 'd']],
... index=['row 1', 'row 2'],
... columns=['col 1', 'col 2'])
... df1.to_excel("output.xlsx") # doctest: +SKIP
To specify the sheet name:
This example is valid syntax, but we were not able to check execution>>> df1.to_excel("output.xlsx",
... sheet_name='Sheet_name_1') # doctest: +SKIP
If you wish to write to more than one sheet in the workbook, it is necessary to specify an ExcelWriter object:
This example is valid syntax, but we were not able to check execution>>> df2 = df1.copy()
... with pd.ExcelWriter('output.xlsx') as writer: # doctest: +SKIP
... 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:
This example is valid syntax, but we were not able to check execution>>> with pd.ExcelWriter('output.xlsx',
... mode='a') as writer: # doctest: +SKIP
... 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 :None:None:`engine` keyword (the default engine is automatically chosen depending on the file extension):
>>> df1.to_excel('output1.xlsx', engine='xlsxwriter') # doctest: +SKIPSee :

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
