Excel File on Samsung J7 has crashed, how can I repair the file?

[Android Central Question]

I can view the file in my Cache, but I am having trouble finding an app that can help repair it

If it's an xlsx file, it's just text, so any text editor can edit it - but you have to know how to repair what's broken. Repairing corrupted xml files (which is what an xlsx file is) automatically isn't normally possible, since no program can "know" what's missing or incorrect.
