As answered by people managing Code Beautify JSON Validator and JSONNorm.
JSONNorm's answer:
jsonnorm focuses on predictable conversion rather than just flattening JSON. It lets you control array behavior per path, distinguishes tricky cases like null vs missing values, preserves large numbers without float rounding, handles changing NDJSON schemas, and previews the output structure before conversion.
JSONNorm's answer:
Choose jsonnorm when the structure of the output matters. It is designed for nested or inconsistent JSON where simple converters can silently change row counts, drop fields, or alter values. It is free, requires no signup, supports large files, and also provides an anonymous HTTP API.
JSONNorm's answer:
Developers, data engineers, analysts, and technical users who need to turn nested JSON, API responses, or NDJSON/JSONL into predictable CSV without writing a one-off conversion script.
JSONNorm's answer:
jsonnorm started from a simple problem: JSON-to-CSV tools work well on easy inputs, but real data often contains nested objects, arrays, changing schemas, nulls, and large numeric IDs. The project was built around making those conversion decisions explicit and predictable instead of hiding them behind defaults.
JSONNorm's answer:
.NET / ASP.NET Core, C#, and a browser-based web frontend.
