Frequently Asked Questions

Why convert CSV to SQL?

CSV (Comma-Separated Values) uses tabular plain text encoding and is best for spreadsheets, database exports, and data imports. SQL (Structured Query Language) uses database query encoding and excels at relational database operations, data analysis, and reporting. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.

How are types inferred?

Integers, decimals, dates, and text detect per column with manual override. Mixed columns fall back to TEXT to preserve data.

Which SQL dialect?

Standard INSERT syntax portable across Postgres, MySQL, and SQLite; quoted identifiers handle reserved words. Adjust sequences after import.

Large CSVs?

Tens of thousands of rows generate fine; wrap output in transactions for fast imports. Million-row files split by key first.

Does SQL generation upload data?

No — conversion runs locally in your browser. Data never leaves your device.
