Excel file and CSV accessibility

Good day everyone,
I have some questions on spreadsheet accessibility. I have checked out various resources such as 508.gov, but the spreadsheet accessibility guidance there doesn't cover our specific issues.

As a statistical agency, we are putting out a lot of .csv and .xlsx files and are trying to 1. Remediate new files for Section 508 conformance and 2. Teaching content contributors to structure and format their files as they are developing them.

We are reformatting the underlying databases to address the data structure which will help, but will take time.
For now, I'm looking for some information on remediating data-heavy excel and csv files.
Thank you,
Lisa
