JSON to SQL Insert
Convert a JSON array into INSERT statements
What is JSON to SQL Insert?
This JSON to SQL converter turns an array of objects into INSERT statements: it collects the column set automatically, renders each literal according to its type, escapes embedded single quotes, and can emit either one statement per row or a single multi-row insert. The conversion runs entirely in your browser.
How to use JSON to SQL Insert
- 1Paste an array of objects.
- 2Enter the target table name.
- 3Choose the output style. The combined multi-row form is more efficient for bulk imports.
- 4Always run the statements against a test database before touching production.
Common errors and how to fix them
| Symptom | Cause | Fix |
|---|---|---|
| Non-ASCII text becomes question marks after the insert | The connection or the table is not using the utf8mb4 character set. | Confirm that the database, the table, and the connection all use utf8mb4 before importing. |
Frequently asked questions
Do the generated statements protect against SQL injection?+
The tool escapes single quotes inside values by doubling them, which yields syntactically valid statements, but this is still concatenated SQL rather than a parameterized query. Use the output for one-off data imports only; application code must always use prepared statements.
How are nested objects handled?+
They are serialized to a JSON string and inserted as text. That is exactly what you want when the target column is a MySQL JSON column. For an ordinary string column, flatten the data first.
