Convert SQL between dialects instantly
Translate SQL queries between MySQL, PostgreSQL, Snowflake, and BigQuery without rewriting them by hand. Handles differences in quoting, function names, date arithmetic, and identifier syntax so you can move queries between databases or data warehouses with confidence.
Frequently Asked Questions
- How does the SQL dialect conversion work?
- Your query is parsed and transpiled using sqlglot, which understands the syntax quirks of each dialect — quoting styles, function names (e.g. IFNULL vs. COALESCE vs. NVL), date arithmetic, and identifier escaping — and rewrites the query for the target dialect.
- Which dialects are supported?
- MySQL, PostgreSQL, Snowflake, and BigQuery. You can convert between any pair, including swapping the direction with the ⇄ button.
- Will every query convert perfectly?
- Most standard SQL — joins, aggregations, filtering, common functions — converts cleanly. Highly dialect-specific features (proprietary functions, stored procedures) may need manual review after conversion.
- Is my SQL sent anywhere other than this tool?
- The query is sent to the Hexabench backend to run the conversion via sqlglot, but it is not stored or logged — nothing is saved after the response is returned.
