Description
From the marketplace listing
Open a CSV file in ChatGPT to view a table, edit CSV cells, fix column headers, add or delete rows and columns, and search for values. Undo mistakes and explicitly save changes to the opened CSV file. File contents stay in the browser and ChatGPT host resource flow; no separate account or database upload is required. Supports files up to 5 MiB, 50,000 cells and 200 columns. Saving requires host write permission and an entity tag. The editor does not evaluate formulas, macros or SQL and does not support Excel workbooks.
