FAQFrequently asked

What is the fastest way to clean a messy spreadsheet with AI?

Upload the file to Claude and describe what is wrong with it in ordinary language. There is nothing to install and no licence to check, and you get a cleaned file back to download. Use Copilot or Gemini instead if the data cannot leave your company systems.

Which tool handles thousands of rows of text?

Numerous.ai. You write the instruction once in a single cell and drag it down the column, which is far cheaper and faster than pasting batches into a chat window. Julius is the better choice if you want analysis and charts rather than edits.
