Gridhand

Describe what you want, such as split the address column, standardize country names or remove duplicate customers, and Gridhand performs it as a list of explicit steps rather than a black-box rewrite. Every step can be inspected, reordered or undone, and the whole recipe can be replayed on next month's export.

Operations analysts, marketers and accountants who receive the same messy export every week use it to stop repeating manual cleanup. It runs in the browser on files up to a million rows and as an add-on for Google Sheets and Excel. Fuzzy matching of names and companies is good but not perfect, so merges are shown for approval before they apply.
