Open the old format without Excel
Legacy .xls files often turn up in archived folders and old shared drives. Drop one into the viewer to read the first sheet in your browser. You can also open a newer .xlsx file here. Sort and filter the table, then export the active view as CSV when you need a format that more tools can open.

The viewer helps you inspect a workbook without installing Excel. Loam connects your files to your AI, so your AI answers from your real data. To try questions in the free chat tool, export this view as CSV and upload that CSV separately. The chat tool accepts CSV and TSV files.
