Overview
JSON to CSV conversion turns structured JSON records into a flat table text format. Rows represent records and columns represent field paths. This makes it easier to open analytics exports, API samples, and configuration snippets in spreadsheet tools without building a custom pipeline.
When flattening is enabled, nested objects become dotted path columns using underscore separators (for example, user.name becomes user_name). Arrays and deep structures that are not simple objects are serialized as JSON text inside a single cell so values remain lossless and readable.
This page is built for local session conversion. Your paste or uploaded file is processed to produce CSV text in-browser; avoid pasting regulated secrets unless your policy allows browser utilities. For large payloads, expect slower typing feedback and consider trimming input.
