Convert CSV to JSON Online

Our CSV to JSON converter transforms comma-separated values into structured JSON format instantly. Whether you're preparing data for an API, migrating databases, or working with JavaScript applications, this tool handles the conversion with full support for custom delimiters and encoding options.

Understanding the Formats

CSV (Comma-Separated Values) is a simple text format where each line represents a row and values are separated by commas or other delimiters. It's widely used for spreadsheet exports, database dumps, and data exchange between applications.

JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write, and easy for machines to parse. It's the standard format for web APIs and modern applications.

Header Row Handling

When "First Row Is Header" is selected, the converter uses the first row's values as keys for the JSON objects. Without headers, the data is converted to arrays of arrays. Choose the option that matches your CSV structure for accurate conversion.

Encoding Options

Different CSV files may use different character encodings. UTF-8 is the most common and handles international characters well. Latin-1 is often used for Western European languages, while ASCII works for basic English text. If you see garbled characters, try changing the encoding option.
