JSON to CSV Converter

This tool converts structured JSON data into CSV rows. It accepts common JSON shapes such as objects, arrays, and nested arrays, and outputs a flat table suitable for spreadsheets, databases, or BI tools.
Core logic uses a two-pass approach: first normalize objects into records, then flatten nested structures by concatenating path keys (or expanding arrays into separate rows). Users can enable or disable headers, choose delimiter, and select flatten strategy.
Who benefits: developers importing API data, data engineers preparing ETL feed, analysts performing quick exports, and teams migrating logs. Unique value: robust handling of irregular JSON, optional schema inference, and deterministic column naming that remains stable across similar inputs.
Core features and use cases: accepts streaming JSON or single-file input, configurable delimiter and quoting rules, optional header row, and output validation against a sample schema. Use cases include API dumps, log aggregation, data migration, and BI-ready datasets.
