Questions & Answers

As answered by people managing JSONNorm and JSONLint.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

JSONNorm's answer

.NET / ASP.NET Core, C#, and a browser-based web frontend.
