Bring your own spreadsheet — pick what to group by, what to measure, and get an interactive report. No fixed template.
Upload one file, or several with the same columns (e.g. Jan.xlsx + Feb.xlsx + Mar.xlsx) — they'll be combined into one report. Works with any spreadsheet: sales, customers, payroll, inventory, whatever you're tracking.
Nothing is uploaded to a server or stored — the same privacy promise as before, now for any data you bring, not just customer lists. Have a messier, multi-source, or genuinely large dataset? Get in touch — that's a job for a real analyst pass, not this in-browser tool.
