About SQLFlow

SQLFlow converts spreadsheet data into SQL. You drop in a .csv or .xlsx file, map the columns, check a free live preview of the generated statements for the first few rows, pay for the conversion and download the script. It can produce insert, update or upsert queries in one click, and no account is needed.

The tool follows a browser-first approach: the file is parsed locally in the browser, and only the column mapping and a reference to the payment session are stored. Download links expire 24 hours after payment. The focus is PostgreSQL syntax including upsert logic, and the plans also list MySQL and T-SQL output, data cleaning and primary key mapping. Pricing is per file and has no subscription: one dollar for up to 100 rows, five for up to 500 rows and fifteen for unlimited rows, which adds direct JSON export and priority processing.
