Files & data
Turn documents and tables into findings you can check against the originals.
You have a PDF, spreadsheet, notes, or a collection of files.
Choose a guide by the result you want. Each one gives you a usable starting prompt, a concrete example and checks that expose weak output before you rely on it.
Which part of the file answers the question?
Ask a bounded question and require page, sheet or row references. Verify numbers, exceptions and tables in the original file before using the result.
Decisions that matter
- Scanned pages and charts can require visual inspection.
- Two versions need a difference table with both locations.
- Share the smallest permitted portion of a file.
