Formula.dog

Formula.dog is an AI tool that turns a plain English description of a spreadsheet problem into a working formula. A user types something like "sum column B only when column A is this week" and receives the formula along with a short explanation, ready to paste into a sheet. The mascot, a dog named Biscuit, is the voice of the product. It covers Excel formulas including LET, LAMBDA and array formulas, Google Sheets formulas including ARRAYFORMULA and QUERY, VBA snippets, regular expression helpers, and basic support for Airtable and Notion formulas. The site states plainly what it does not handle: Power Query, Power BI DAX, and Python or R. The formulas come from a fine tuned model, and the site offers a playground, a cheat sheet and a set of written lab notes alongside the generator. The tool is aimed at spreadsheet users who know what result they want but not the syntax, such as small business owners, analysts and office workers. No account is needed to use the free tier, and the vendor says it does not ask for an email address before showing a formula. Pricing is published in three options. The free tier costs $0 and allows 5 formulas a day with no account. A Pack of 100 costs $5 as a one time purchase, with 100 formulas that never expire and no subscription. The unlimited plan costs $8 per month and adds unlimited formulas plus history and bookmarks, and it can be canceled at any time. There are no annual discounts or enterprise plans. Formula.dog began in 2022 as a weekend project and was relaunched in early 2026 with a new design and Google Sheets support. It is run by one person based in Lisbon, Portugal.
