CSV (Comma-Separated Values) is common for spreadsheets and data exports. JSON (JavaScript Object Notation) is standard for APIs and web applications. Converts CSV data into structured JSON using the first row as property keys. Handles quoted fields, custom delimiters, and line endings.
Paste your CSV data into the input field or drag and drop a .csv file. The tool uses the first row as JSON property keys and converts each subsequent row into a JSON object. You can customize the delimiter (comma, tab, semicolon, pipe). The result is an array of objects that can be copied to clipboard or downloaded as a .json file.
CSV-to-JSON conversion is essential when importing spreadsheet or database exports into web applications, feeding data into JavaScript visualization libraries like D3.js or Chart.js, preparing data for REST API consumption, migrating data between systems that use different formats, and transforming flat tabular data into structured documents for MongoDB or other NoSQL databases.
The parser handles RFC 4180 compliant CSV including quoted fields containing commas and newlines, escaped double quotes within quoted fields, and different line endings (CRLF, LF). All values are kept as strings. The tool processes everything in-memory using JavaScript string operations with no external dependencies.
Paste your CSV data into the input field. The tool uses the first row as JSON property names and converts each subsequent row into a JSON object. The result is a JSON array of objects that you can copy or download.
Yes. Fields enclosed in double quotes are parsed correctly, including fields that contain commas, newlines, or escaped quotes within them, following the RFC 4180 standard.
Yes. You can specify tab, semicolon, pipe, or any custom delimiter. The tool also attempts to auto-detect the delimiter based on the input data.
You can either paste CSV content directly or drag and drop a .csv file onto the input area. The file is read locally - nothing is uploaded to any server.
