LocalKitAbout JSON to CSV
JSON records often come from an API or database. An array of objects becomes a CSV table using the union of keys as columns; nested values are stored as JSON text.
Why convert JSON to CSV?
CSV lets you inspect API records in spreadsheet software. Missing properties become empty cells.
