SQL Cell brings a real SQL engine into Google Sheets™. Query files with DuckDB, preview the results, and write them straight into your spreadsheet.

Your files are read where they sit. SQL Cell runs DuckDB inside the sidebar, in your browser — there is no SQL Cell server to upload them to.

WHAT YOU CAN QUERY

Query around 35 file and data formats, including CSV, TSV, Parquet, JSON, JSONL, Excel, Avro, Arrow, XML, YAML, Markdown, SQLite, DuckDB, Shapefile, GeoJSON, GeoPackage, KML and Power BI models.

Read data from your machine, any HTTPS URL, S3, Cloudflare R2, Google Cloud Storage and other S3-compatible storage. SQL Cell also supports Iceberg tables, DuckLake catalogs and MotherDuck.

No conversion step. No importing the source data into Sheets first.

REAL SQL, DIRECTLY IN SHEETS

• Full SQL — joins, CTEs, window functions, aggregates and more. This is DuckDB SQL, not a simplified query language.

• Preview before writing — inspect the result and choose the destination cell before anything is inserted into your spreadsheet.

• Overwrite protection — if existing cells are in the way, SQL Cell counts them and asks before replacing anything.

• Column profiling — inspect ranges, distributions, unique values and nulls before writing a line of SQL.

• Query provenance — every result remembers the SQL that produced it, visible from the formula bar even months later.

• Workbook history — see every result SQL Cell has written in the current spreadsheet, jump back to it or run the query again.

• Built for large data — query millions of rows without first squeezing the source data into a spreadsheet. Large results are written in one pass with live progress.

FREE, WITH AN OPTIONAL PRO UPGRADE

Everything above is free.

SQL Cell Pro adds persistent connections, files and history for people who use SQL Cell regularly:

• Saved connections — save credentials for S3, Cloudflare R2, Google Cloud Storage, HTTPS, Iceberg, DuckLake, Quack and MotherDuck. They are restored automatically when the sidebar opens.

• Kept files and folders — keep local files and folders attached between sessions instead of selecting them again each time. Available in Chrome and Edge.

• Workspace history — see every result you have written with SQL Cell across all your spreadsheets, not just the workbook currently open.

• Execution log — review what you ran, how long it took and what failed.

SQL Cell Pro is a one-time purchase and includes 12 months of updates. One licence covers three Google accounts.

WHY SQL CELL?

Most SQL add-ons are database connectors: provide database credentials, connect to a remote server and query it.

SQL Cell is different. It lets you query files and analytical data sources directly — whether they are on your machine, behind an HTTPS URL, in object storage or in a data catalog.

For a local file or public URL, there is nothing to configure. Open SQL Cell, attach the data and start querying.

PRIVACY BY DESIGN

SQL Cell runs in your browser. It has no backend, contains no analytics, and does not send your spreadsheet contents or source files to SQL Cell servers.

Pro connection details, history and execution logs are stored in your own Google account and can be deleted by you. The only Pro information sent outside the browser is the licence key used to verify your purchase with our payment provider.
