Excel
XLSX is the default workbook format of Microsoft Excel. It stores typed cells, multiple sheets, and formatting in a compressed container, and is the lingua franca of business reporting and data exchange.
SQL
SQL INSERT scripts let you load tabular data straight into a relational database such as MySQL or PostgreSQL. Each row becomes part of a batched INSERT statement that you can run in any database client.
How the Excel to SQL conversion works
Your .xlsx or .xls workbook is parsed on your device; choose a sheet if there are several. The header row becomes the column list, quoted per dialect — backticks for MySQL, double quotes for ANSI databases like PostgreSQL.
Cell types drive the SQL: numbers stay bare, dates become ISO strings, empty cells become NULL, and text is escaped with doubled single quotes. Rows are grouped into multi-row INSERTs of up to 500 rows for fast execution.
Frequently asked questions
- Which sheet gets converted in a multi-sheet workbook?
- The first sheet by default — a selector appears when the workbook has more than one, and the preview re-parses as soon as you pick another.
- Are values like O'Brien escaped correctly?
- Yes: embedded single quotes are doubled per the SQL standard, and the MySQL dialect additionally escapes backslashes, so the script runs cleanly.
- Do formulas end up in the SQL?
- No — each formula cell contributes its last computed value, which is what you want in a database insert.
- Does the spreadsheet leave my machine?
- Never. Parsing and script generation happen in a Web Worker in your browser — free, with no account required.
