JSON to CSV

CSV and JSON model data very differently: CSV is inherently a flat, two-dimensional grid of rows and columns, while JSON supports arbitrarily nested objects and arrays. Converting an array of JSON objects to CSV means flattening that structure — each object becomes one row, and its keys become column headers, with values placed under the matching column.

This conversion is common when data produced by an API or a script (naturally JSON) needs to be opened in a spreadsheet application, imported into a tool that only accepts CSV, or shared with someone who isn't going to parse JSON by hand. It's especially useful for exporting logs, survey responses, or database query results for analysis in Excel or Google Sheets.

Because CSV has no native way to represent nested structures, objects that aren't flat need special handling — this tool converts any nested object or array value to its string representation rather than expanding it into further columns. It also follows standard CSV quoting rules so that values containing commas, quotes, or newlines round-trip correctly.
