What is csv to json converter?
CSV is the lingua franca of spreadsheets; JSON is the language of APIs. Moving data between the two is a daily task for developers, analysts, and marketers alike.
This converter parses your CSV into clean JSON objects using the header row as keys — or flattens a JSON array back into a spreadsheet-ready CSV. Quoted fields, embedded commas, and newlines are all handled correctly, and nothing leaves your browser.
How to use it
-
Paste your CSV
The first row is treated as column headers. Semicolon and tab delimiters are detected automatically.
-
Switch direction

-
