AI Spreadsheet Formula & Data Analysis Tool
Turn plain-English requests into Excel/Sheets formulas, then upsell AI data analysis.
In plain English
A plain-English request becomes an Excel or Google Sheets formula on David Bressler's site, where a free page lets people try it and paying opens unlimited use. From there the offer grows into AI help for understanding the numbers in the sheet, add-ons inside Excel and Google Sheets, and a way to chat with your own numbers. They pay a subscription because writing formulas and reading a big sheet by hand is slow. The AI does most of the formula writing and the billing, while David still makes deals with people who have an audience, expands the product, and answers support questions.

Overview
Turn plain-English requests into Excel/Sheets formulas, then upsell AI data analysis. Operator: David Bressler.
Realistic income
Reported: $26K MRR (2024), then $500K ARR (May 2025, self-reported). This is one operator’s result and doesn’t predict yours.
Risks
- Excel and Google Sheets now ship their own formula helpers, which can remove the reason to open a separate site.
- A free tool can go viral before a paywall exists, and the API bill shows up first.
- The useful version is the one inside the spreadsheet. An add-on review or a platform rule change can cut distribution.
*Income figures are illustrative ranges based on public pricing and typical outcomes reported by practitioners, not guarantees. Most new online businesses earn little or nothing at first. Not financial, legal or tax advice.
