About
A small studio for dependable spreadsheet tools.
Cellbrook is the product brand of MRSLM Group LLC, a Florida limited liability company. We build focused add-ons for Google Sheets that people can trust with real work.
What we believe
Spreadsheet add-ons often hide their limits, overcharge, or make cancelling hard. We think tools should be clear about what they do, what they cost and where your data goes, and should let you leave easily.
- Narrow scope. Each add-on asks for the fewest Google permissions it can.
- No data hoarding. We run no database of your spreadsheet content.
- Honest pricing. Tax-inclusive prices, one-click cancellation and a 14-day refund on first payments.
