❓ Frequently Asked Questions
What JSON structure is supported? ▾
The tool expects a JSON array of objects where all objects share the same keys. Keys become column names and values become the insert values with appropriate SQL quoting.
How are different data types handled? ▾
Strings are wrapped in single quotes with escaping. Numbers are inserted as-is. Booleans become TRUE/FALSE (or 1/0 for MySQL). NULL values become SQL NULL.
Can I specify a custom table name? ▾
Yes — enter your table name in the "Table Name" field above. The default is "my_table". The table name is applied to all generated INSERT statements.
