FAQ

QCan VBA run in the browser?

No. VBA runs only in desktop Excel; this tool generates and optimizes code only.

QHow is this different from online Excel tools?

Online tools for one-off jobs; VBA for repeat automation. Try online dedup/merge for preview workflows.

QIs my data uploaded?

VBA drafts stay in browser localStorage. AI uses your own API key per request—it is not stored on our servers.

QWhere are the guides?

See VBA guide links below, e.g. /vba-loop-through-rows, /vba-merge-workbooks.

Getting started with VBA automation

Alt+F11 → Insert Module → paste code → run Sub. See /how-to-write-vba, /vba-for-beginners; for online dedup see /excel-remove-duplicates.
