Sourcetable Inc. is looking to eliminate the technical barrier in spreadsheets that separates so-called “power users” from those who can just about work out how to use the Sum key to add up the value of entries in a single column. At the heart of Sourcetable is what the company describes as a “fast, accurate code-driven evaluation loop” that can verify the underlying LLM’s responses in real time to ensure the accuracy required for complex, multistep automation tasks. This ensures that users can trust that the insights it generates are accurate, founded in the actual data within the spreadsheet. With Sourcetable, users simply tell the spreadsheet what they’re trying to achieve using their natural language. It supports both keyboard commands or voice, similar to the emerging practice of “vibe coding,” which is where a developer describes a problem in a few sentences in order to prompt a large language model to generate code. The startup describes its product as the first “self-driving” spreadsheet with autopilot capabilities, with the underlying AI having full write and editing access to each file so it can perform complex, multistep tasks on behalf of users. Among other things, Sourcetable can create and edit financial models, create charts and graphs based on spreadsheet entries, build pivot tables, clean data, edit the formatting, enrich the data within a column, or analyze an entire workbook and summarize its contents.
