Frequently Asked Questions
Does the JSON Formatter validate my JSON?▼
Yes. The formatter parses and re-renders the JSON — if your data has a syntax error, it highlights the location of the error so you can fix it immediately.
Can I convert between JSON and CSV?▼
Yes. Use JSON → CSV to turn a JSON array of objects into a spreadsheet-ready CSV file, or CSV → JSON to do the reverse. Both tools handle nested structures and special characters.
What SQL dialects does the SQL Formatter support?▼
The SQL Formatter supports standard SQL syntax compatible with MySQL, PostgreSQL, SQLite, and SQL Server. It handles JOINs, subqueries, CTEs, and window functions.
Is my data safe when using these formatters?▼
Completely safe. All formatting and conversion runs in your browser using JavaScript — your data is never uploaded to any server or stored anywhere. You can even use these tools offline after the page loads.
