Large Data Analysis Workbench
Ask your data a question in plain English — a free Windows app
Free · Windows · Microsoft Store Describe what you want and the app writes the prompt for you. Paste it into ChatGPT, Claude or Copilot, paste the reply back, and the query runs on your machine. You do not need to know SQL — and the app never contacts an AI itself, so nothing about your data goes anywhere unless you send it yourself.
- Run several checks at once, every result on its own sheet of one workbook
- Save a set of checks and re-run it on next month's file
- Filter, look up, de-duplicate, pivot and profile
- Runs entirely offline — files are never uploaded, no telemetry
- total NetAmount by Vendor, biggest first
- rows where InvoiceNo is empty or missing
- how many rows for each Category
- the 20 rows with the highest NetAmount
The prompt carries your question and the column names, with example formats redacted. No values from inside your file.
