CSV to JSON Converter

What is a CSV to JSON Converter?

CSV stores tabular information in rows and columns. JSON stores structured information using objects and arrays. This converter turns each CSV row into a JSON object and keeps the first row as property names by default.

CSV

name,age,city
Alice,28,Bengaluru
Bob,35,Mumbai

JSON

[
  {
    "name": "Alice",
    "age": "28",
    "city": "Bengaluru"
  },
  {
    "name": "Bob",
    "age": "35",
    "city": "Mumbai"
  }
]

When automatic type detection is enabled, obvious values such as numbers, booleans, and null can become real JSON values instead of strings.

How to convert CSV to JSON

1. Paste CSV data or upload a CSV file.
2. Confirm whether the first row contains headers.
3. Select or auto-detect the delimiter.
4. Adjust data type and formatting options if needed.
5. Convert the CSV and copy or download the JSON.

CSV to JSON conversion options

The converter supports headers, custom delimiters, quoted values, whitespace trimming, empty-row skipping, data type detection, and JSON indentation so it adapts to common spreadsheet and export formats.

Common uses for CSV to JSON conversion

• Converting spreadsheet exports for APIs and apps.
• Preparing seed data for local development.
• Migrating data between systems.
• Creating JSON configuration files from tables.
• Testing applications with realistic sample data.

Is CSV to JSON conversion private?

Conversion happens entirely inside the browser. CSV files are not uploaded to a server and the tool does not store your data. You should still avoid sharing sensitive information on untrusted devices.
