Questions & answers
01Can nested JSON be represented in CSV?
Only partially. CSV is flat, so nested objects must be flattened into dotted column names or serialized into a single cell. Arrays of flat objects convert cleanly: each object becomes one row.
02Does this upload my data?
No. This utility runs in the browser and only produces a local text output.
03Is JSON to CSV free to use?
Yes, JSON to CSV is completely free, with no sign-up and no usage limits. It runs entirely in your browser, so your data never leaves your device.
