How to choose
For quick analysis of a file, upload it to ChatGPT or Claude and ask. For spreadsheet work, use Gemini (Sheets) or Copilot (Excel). For heavier or repeatable analysis, code tools help. Always sanity-check AI’s numbers and methodology — it can make analytical errors and confidently present wrong figures.
