JSON to SQL: Load a Test Dataset Without a Migration

September 12, 2026

Seeding a staging table usually means writing INSERT statements by hand or fighting an ORM seeder for throwaway data. When the data already exists as a JSON array, converting it directly is the honest shortcut.

Paste a JSON array of objects and it emits SQL INSERT statements with the keys as columns. Review the output before running it, and it becomes a quick fixture for local tests.
