Questions & Answers

As answered by people managing Tellsheet.
  1. How would you describe the primary audience of Tellsheet?

    Everyday Excel users who spend time cleaning and reshaping data — finance, operations, sales, HR, and analysts. It's built for point-and-click use, not for developers, with an optional AI command bar for plain-English requests.

  2. What makes Tellsheet unique?

    Tellsheet previews every change before it touches your sheet, and runs entirely on your computer — your data is never uploaded. It brings dozens of point-and-click tools for cleaning and reshaping data, plus an optional plain-English AI command bar, to Excel on Windows, Mac, and the web alike.

  3. Why should a person choose Tellsheet over its competitors?

    Most Excel add-in suites are Windows-only and sold as recurring or high-priced licenses. Tellsheet works the same on Windows, Mac, and Excel on the web, is a one-time $39 purchase with a permanent free tier — no subscription — and shows a preview plus one-click revert for every change, so you never have to trust it blindly.

  4. What's the story behind Tellsheet?

    Tellsheet started from doing the same tedious Excel cleanup by hand over and over — splitting name columns, removing duplicates, reconciling two lists, fixing garbled text. We built one add-in that does all of it in a click, works everywhere Excel does, and keeps your data on your own machine. Made by Souq E Kamil Trading and Solutions WLL in Bahrain.

  5. Which are the primary technologies used for building Tellsheet?

    An Office.js add-in with a React/TypeScript task pane, so it runs across Excel on Windows, Mac, and the web. Licensing is self-hosted on Cloudflare Workers + D1; payments are handled by Paddle as merchant of record. The optional AI command bar uses your own Anthropic API key.

  6. Who are some of the biggest customers of Tellsheet?

    Tellsheet is a privacy-first, on-device Excel add-in — every tool runs locally on the user's own computer and their spreadsheet data never leaves it, so by design we don't track, profile, or collect who our users are. That means there's no customer database to mine for a "logo wall," and we wouldn't publish one even if there were. In practice, Tellsheet is used by the people who live in messy spreadsheets: individual analysts, accountants, and finance/operations professionals, plus small teams doing repetitive data cleanup — splitting names, removing duplicates, unpivoting, reconciling two sheets, fixing garbled text. It's available worldwide through Microsoft AppSource and runs on Windows, Mac, and Excel on the web.
