Some PyXLL features will add XML metadata to the Excel workbook when saving.
Features that use this metadata are:
Metadata used by PyXLL is added to the workbook as a CustomXMLPart, which is part of the workbook document.
The CustomXMLPart is saved in the workbook using an XML namespace specific to the PyXLL add-in so
as not to conflict with data saved by other add-ins. If you have specified a name for your add-in using
the name setting that will be used to avoid conflict with any other PyXLL add-ins you may have loaded.
If you prefer to specify the namespace to use instead of having PyXLL use it’s own namespace you can
do so by setting metadata_custom_xml_namespace in the PYXLL section of your pyxll.cfg file.
[PYXLL]
metadata_custom_xml_namespace = urn:your_name:metadata
To disable writing any metadata you can set disable_saving_metadata = 1 in the PYXLL section
of your pyxll.cfg file. Note that this will affect all PyXLL features that require metadata.
[PYXLL]
disable_saving_metadata = 1
