DeepTable – an API that converts messy Excel files into structured data
We tried to build an Excel error checker. To achieve that, we needed to actually understand the semantic structure of a spreadsheet first. So we built that, and it turned out to be the harder, more general problem. The core issue: most real-world spreadsheets aren't relational tables. Merged cells, multi-level headers, multiple tables per sheet, totals mixed in with data. You can't just dump them to CSV and call it done. LLMs handle the easy cases but fall apart on complex workbooks at scale. Our approach uses an agent-guided compilation pipeline that produces SQL-ready relational tables…

What it does
Turn a messy spreadsheet into a clean SQLite database.
In this tutorial, you’ll upload a spreadsheet, convert it into a structured sheet, and download it as a SQLite database and individual CSV files. pip install deeptable Terminal window npm install @deeptable/deeptable Terminal window go get github.com/deeptable-com/deeptable-go Terminal window go install 'github.com/deeptable-com/deeptable-cli/cmd/deeptable@latest' If the deeptable command isn’t found after installation, add the Go bin directory to your PATH: export PATH = " $PATH :$( go env GOPATH)/bin" 2. Set your API key Section titled “2. Set your API key” Terminal window export DEEPTABLE_API_KEY = "your-api-key" 3. Download an example spreadsheet Section titled “3.

OpenSheetFeb 2026 · opensheet.app · ▲86Hi folks. I've been doing some experiments on how LLMs could get more handy in the day to day of working with files (CSV, Parquet, etc). Earlier last year, I built https://datakit.page and evolved it over and over into an all in-browser experience with help of duckdb-wasm. Got loads of feedbacks and I think it turned into a good shape with being an adhoc local data studio, but I kept hearing two main things/issues: Why can't the AI also change cells in the file we give to it? Why can't we modify this grid ourselves? So besides the whole READ and text-to-SQL flows, what seemed…

Hi HN! I’m Eoin, founder of Sourcetable (https://sourcetable.com). Sourcetable is an AI-native spreadsheet that syncs with all your data. Users pair with an AI copilot that helps them do their spreadsheet work, as well as more database-centric analysis and SQL. Soucetable syncs with databases including Postgres, MySQL, and MongoDB, and over 100+ business applications including Stripe, Zendesk, Hubspot, Quickbooks and Google Analytics. That data is available in a spreadsheet, and any models you build automatically update in near-real-time as new data flows in. The core primitives…
Sourcetable - AI spreadsheet2024 · sourcetable.com · ▲49We built what we're calling "operational spreadsheets" – spreadsheets that can actually execute actions across external systems, not just calculate and display data. The core idea: spreadsheets have been passive tools for 40 years. You put data in, formulas process it, you export it, manually move it somewhere else, repeat. We added bidirectional API integration with natural language commands, so the spreadsheet itself can send emails, update databases, orchestrate workflows across services – autonomously. Think of it as the evolution from VisiCalc → Excel → Google Sheets (multi-user) →…
