FAQ

How does the converter handle nested JSON structures? Our parser recursively flattens nested JSON dictionaries into flat headers separated by dots (e.g. 'user.profile.name'), mapping them directly into a two-dimensional CSV structure.

Will arrays or lists stay formatted correctly? Single values or lists of primitives are converted to string format, while arrays of objects are structured in flat rows using their child keys.

Is my data uploaded to servers safely? Yes, we prioritize security. All uploads and generated files are automatically and permanently deleted from our servers after exactly 1 hour. No backups, cache, or logs are retained.
