About these converters

Data rarely arrives in the format you need. A spreadsheet has to become INSERT statements, a database dump has to open in Excel, a YAML config has to become TOML, or an API response has to be shared as a workbook. These converters handle those jobs in one paste.

SQL tools generate and read INSERT statements for MySQL, PostgreSQL, SQLite and SQL Server and format long queries. Format converters cover CSV, TSV, Excel, YAML, XML, TOML, Markdown and HTML tables, and config tools read .env, INI and URL query strings. Everything is converted in your browser, so dumps, exports and secrets never leave your device.
