Ask across the workspace. It runs real queries and writes output files.
The agent reads both files, finds the join key, runs the merge, and writes a new .xlsx into your folder. You see the row counts before and after.
Runs the filter against the real data, not a sample. Returns the matching rows with the exact numbers. You can copy the result or export it.
Strips whitespace, lowercases, deduplicates, groups by domain, and writes the result. Every step is visible: what it did, how many rows changed, what the output looks like.
The web version is a capped browser preview. The desktop app adds folder mode, live file watching, and no browser quota. The Mac release is coming soon for $19.99 on the Mac App Store.
Paid Mac app for serious spreadsheet work. Private by default, folder-based, and not capped by the browser.
Fast browser preview for quick trials. No install, no key setup, just upload a few sheets and try the workflow.
