The row shape is deterministic
The first object defines column order. Every following object must contain exactly the same keys before SQL is generated.
- Input
- JSON
- Dialects
- 4 explicit
- Runtime
- Browser
Generate a literal SQL INSERT from flat JSON
Serialize uniform flat JSON rows into a dialect-quoted literal INSERT and validate the generated SQL locally.

Generate SQL INSERT
Inputs stay in this browser tab. Parser-heavy work uses a tighter 256 KiB safety cap.
Generated INSERT
No result is placed in a URL, account, API, or remote log.
What this tool does
Bounded, explicit-dialect processing
JSON objects must share one property set and contain only strings, finite numbers, booleans, or null. Nested objects and arrays require an application-specific mapping and are rejected.
Generated SQL still needs review
Literal output can be large and may not be the right ingestion method. The tool never sends, executes, or imports the statement.
The parser runs locally under byte, statement, AST-node, depth, row, column, diagnostic, and output limits. It never connects to a database or resolves files and URLs.
