About
JSON to CSV flattens a JSON array of objects into a table on your computer. Columns are the union of all keys in first-seen order; missing keys become empty cells; nested objects and arrays are embedded as JSON strings so nothing is lost silently. Output is UTF-8 with BOM, so Excel opens Cyrillic without import wizards.
Free converts 5 files a day with a comma delimiter. Pro removes the limit and adds semicolon/tab options. One key covers up to 3 Windows PCs.

FAQ
Is anything uploaded?
No. The app works fully offline; only license activation and update checks touch the network.
My JSON is one big object, not an array. Will it work?
No — the tool expects an array of objects and tells you so honestly instead of guessing.
What do I get after payment?
A license key that unlocks Pro on up to 3 Windows machines for 12 months.
