About This Tool

Paste CSV data or upload a .csv file and convert it to JSON format. The delimiter is auto-detected (comma, tab, semicolon, or pipe) but can be set manually. Choose between an array of objects (using the first row as headers) or an array of arrays. The result can be copied or downloaded as a .json file.
