XLSX not uploading to vectorstore/Assistant API files


When I upload an xlsx (excel file) it says it’s not supported, but when I open the given link for supported files, it includes xlsx (excel file) as supported. Please fix this bug.

Thank you.

The types of files that are supported for the file search method are changed. The link is inaccurate.

If the document contains a two dimensional table, this can be exported to csv, and then uploaded as a file with .txt extension for AI understanding.

Spreadsheet files can have multiple pages, macros, and formula-derived cells that would make document extraction to text the AI can understand impossible.

But it’s not giving proper answers, seems like it doesn’t understand the table structure in that txt format.
