local .xlsx file modified without any change

[jmn2017]

“I am using Sourcetree software to manage my project, which includes Excel files (.xlsx). When I haven’t made any changes to the local xlsx files, the software always prompts me that some .xlsx files have been modified, marked with a yellow icon. I want to know how to solve this situation?”

What does a diff of those files show?

And does the modification of the files change?

Git is normally not used for spreadsheets and other binary files. It is made to detect text based changes.
