How to use

Select Load example to restore the sample, or replace the labeled inputs with your own values.
Review the options and select Run tool. No input is sent to a server.
The union of record keys defines columns; missing properties become SQL NULL. This tool does not execute SQL.
Inspect the result, then copy or download it. Clear removes visible inputs and output.

A worked example

Load example restores these values.

JSON array of records:
[{"id":1,"name":"O'Brien","active":true},{"id":2,"name":null,"active":false}]

Table name:
users

SQL dialect:
PostgreSQL

Expected result

INSERT INTO "users" ("id", "name", "active") VALUES
(1, E'O''Brien', TRUE),
(2, NULL, FALSE);

Scope & limitations

Scalar values only, maximum 1,000 rows. MySQL strings use UTF-8 hex conversion to avoid backslash-mode ambiguity. Review generated SQL against your database and use parameters in application code. JSON numbers use JavaScript binary64 precision; keep large exact identifiers as strings. Numeric overflow is rejected.
