CSV to JSON Converter
Convert CSV data to JSON — paste your CSV, get instant JSON
How to Use the CSV to JSON Converter
- Choose direction (CSV → JSON or JSON → CSV).
- Select the delimiter used in your CSV (comma, semicolon, tab, pipe).
- Paste data and click Convert.
CSV → JSON uses the first row as headers and produces an array of objects. JSON → CSV requires an array of flat objects. Handles quoted fields with commas and newlines correctly.
What is CSV to JSON Conversion?
CSV (Comma-Separated Values) is a plain text format for tabular data where each row is a record and columns are separated by commas. JSON is a hierarchical key-value format. Converting CSV to JSON maps each row to a JSON object, using the header row as keys — making CSV data ready for use in JavaScript, APIs, and NoSQL databases.
Common Uses
- Importing spreadsheet data into a JavaScript application or API
- Converting database exports for use in MongoDB or other document databases
- Transforming analytics exports (Google Analytics, Mixpanel) into JSON for processing
- Preparing data for REST API payloads
Frequently Asked Questions
What happens if my CSV has commas inside a field?
Fields containing commas should be wrapped in double quotes in valid CSV. The converter handles quoted fields correctly, e.g. "Smith, John" remains one field, not split into two.
Does the converter handle CSV files with different delimiters (TSV, semicolon)?
Most CSV converters handle standard comma-delimited files. For TSV (tab-separated) or semicolon-delimited files, check if the tool has a delimiter option or manually replace the delimiter before pasting.
Can I convert JSON back to CSV?
Yes. CipherKit supports bidirectional conversion. Paste JSON (an array of objects with consistent keys) and convert it to CSV format with headers derived from the object keys.
