Talarian

Talarian makes Autosheet (formerly GPT for Work), an AI add-on for Excel and Google Sheets that automates formulas, formatting, analysis and bulk data tasks. The company also builds YAMM, Awesome Table and Form Publisher, with over 60 million installs across its products.

Talarian is the Paris-based software company behind Autosheet, the product formerly known as GPT for Work. Autosheet brings AI directly into Excel and Google Sheets, letting users automate formula writing, formatting, analysis and bulk data work without leaving the spreadsheet. The pitch is straightforward: instead of copying data into a chat window and pasting results back, you describe what you need in plain language and let the add-on handle the repetitive work across rows and columns. The tool suits finance teams, operations staff, analysts and anyone who spends hours on spreadsheet chores. It is especially relevant for people who already live in Google Workspace or Microsoft 365 and want AI assistance without adopting a separate analytics platform. In practice, Autosheet sits inside the grid: you write a prompt in a cell or open the sidebar, point it at a range, and the add-on returns formulas, cleaned values, summaries or reformatted tables. Because it works where the data already lives, there is no export step and no new dashboard to learn. Talarian has been building spreadsheet add-ons since 2011, when its mail merge tool YAMM started as a free Apps Script. The company now reports more than 60 million installs and over 100,000 customers across its product line, which also includes Awesome Table for data connectors and catalog apps, and Form Publisher for generating documents from Forms or Sheets. That track record matters: Autosheet is one product in a mature portfolio, not a standalone experiment. The trade-off is that Autosheet is tied to the spreadsheet environment and the AI provider behind it, so very large datasets, complex multi-source models or highly regulated workflows may still call for a dedicated BI or data preparation tool. For everyday formula and cleanup work, though, it removes a lot of manual copying.
