Excel file size changed in the Sharepoint library

Question

I mapped a sharepoint library to a network drive. When I upload local excel files to that sharepoint library. The files sizes between the local drive and the sharepoint site are dfferent.

Answer 1

Personally I really find it annoying that files are being altered just when uploading to the cloud.

This "feature" makes it impossible to e.g. compare with some merging tools to check if something has changed.

It even comes before the analyzing feature of the content... (e.g. scanning pictures)

Answer 2

@lcha

Yes, the file size will change.

This is because while uploading files to SharePoint Document Library, SharePoint stores the associated column and column value of the file in the file. So you will find that the file size has changed.

Answer 5

I wrote an automatic upload API

When a file is uploaded, it expects the filesize returned by the upload to be the same as the original file.

Unfortunately, for office documents, this feature prevents the API from being sure that the file has been sent correctly
