All SQL parsing and JSON generation run 100% locally in your browser memory. No database dumps, records, or credentials are transmitted over the network.

Frequently Asked Questions

Is my database data uploaded to any server?
No. All parsing and conversion are executed 100% locally in your web browser using client-side JavaScript. Your database records, private credentials, and customer data never leave your computer.
What SQL statements are supported?
The converter supports standard SQL INSERT INTO statements, including single-row inserts, multi-row bulk VALUES clauses, backtick or quote-escaped column and table names, and multi-table database dumps.
How does the parser handle NULL values and escaped quotes?
SQL NULL is automatically converted to native JSON null. Escaped quotes such as ' or SQL-standard doubled single quotes '' are accurately unescaped into normal text strings.
Can I convert multi-table SQL exports?
Yes. When your input contains statements from multiple tables, selecting the Grouped by Table output mode organizes your records into top-level keys for each table.
