What is CSV to JSON Converter?
A CSV to JSON converter takes comma-separated values data, typically exported from spreadsheets or databases, and transforms it into a structured JSON array of objects ready for use in APIs, applications, and scripts.
CSV is the universal export format for Excel, Google Sheets, database dumps, and analytics platforms, but modern web applications and APIs consume JSON. Manually converting rows and columns into nested JSON objects is tedious and error-prone. This tool parses your CSV input using a proper state-machine parser that correctly handles quoted fields containing commas, escaped double quotes, and multi-line values. The first row is automatically treated as column headers, and each subsequent row becomes a JSON object with those headers as keys. You can choose 2-space or 4-space indentation for readable output, then copy or download the result as a .json file. All processing happens in your browser, so your spreadsheet data stays private. Perfect for developers importing CSV data into MongoDB, building API request bodies, or converting legacy data exports into modern JSON format.
How to use CSV to JSON Converter

Copy CSV content from your spreadsheet, database export, or text file and paste it into the input area. The first row should contain column headers that will become JSON keys.
- 2
Choose JSON indentation
Select 2-space or 4-space indentation for the output. The JSON array is generated instantly as you paste, with each CSV row converted to a JSON object using the header row as property names.
