How this tool works
Parses real CSV
Quoted values, commas inside quotes, escaped quotes and semicolon-separated files are handled.
Infers column types
Integers, decimals, booleans, dates and timestamps are detected; everything else is text.
Batches inserts
INSERT statements are grouped by 500 rows, with values escaped safely.
Frequently asked questions
How are column names cleaned?
Lowercased, with spaces and symbols turned into underscores, so "company size" becomes company_size.
Is there a row limit?
The first 2,000 rows are converted, which keeps the browser responsive. Split bigger files.
Is my data uploaded?
No, conversion happens in your browser.
