JSON to Prisma Schema Generator
Turn sample JSON into a Prisma model in one click
Runs 100% in your browser — nothing is ever uploaded.
What is JSON to Prisma?
Paste a sample record and get a Prisma schema model: Int, Float, String, Boolean and DateTime types are inferred automatically, an id field with autoincrement is added when missing, and ISO date strings become DateTime. Paste the result into schema.prisma and keep building — no manual typing of field lists.
How to use JSON to Prisma
- Paste your JSON into the input box or click “Load sample” to try it.
- Adjust the options in the toolbar if needed (root name, format, delimiter …).
- Click the convert button — the Prisma output appears instantly in the output pane.
- Copy the result with one click or download it as a file.
