A more useful json to csv converter
Turn arrays of JSON objects into spreadsheet-ready CSV. Nested keys are flattened, missing values stay aligned and the delimiter can be changed before download. Rantey keeps the core action immediate while showing enough detail to catch common mistakes before the result is used.
Private, fast and designed for mobile
The calculation or conversion happens in your current browser tab. Keeping the operation on the device avoids a round trip to an application server and helps protect source text and files. The interface uses readable labels, large touch targets and stacked controls on smaller screens.
Check the result before you use it
Automated output should still be reviewed when it affects production data, security, billing, schedules or important files. This page exposes validation messages, summaries or formulas where relevant so the result is easier to understand instead of acting like an unexplained black box.
