Ajelix
Use it narrowly, as a formula and macro translator for when you know the outcome you want but not the syntax. The newer agentic-workspace framing puts it up against far better-funded BI tools, and $39 is steep for the one job most people came for.
Pros
- an Excel add-in and Google Sheets add-on keep the work inside the spreadsheet
- handles both directions: generating formulas and explaining existing ones
- tier limits are stated concretely as file size, storage and CPU/RAM instead of vague credits
- covers Apps Script and VBA, which most spreadsheet assistants ignore
Cons
- 10 free requests a month is barely a trial
- $39 entry is expensive next to Copilot or a general assistant doing the same formula work
- no public API despite the automation and agent positioning
- the dashboard and app-builder features are shallow compared with dedicated BI tooling
