About CSV to JSON Conversion
CSV (Comma-Separated Values) is a simple file format used to store tabular data, such as a spreadsheet or database. JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate.
Converting CSV to JSON is useful when you need to:
- Process CSV data in JavaScript applications
- Transform tabular data for use in APIs that require JSON
- Convert spreadsheet exports for use in modern web applications
- Prepare data for storage in NoSQL databases like MongoDB
How This Tool Works
This tool parses your CSV data and converts it to a JSON array. If your CSV has headers (column names in the first row), each row will be converted to a JSON object with properties named after the headers. If your CSV doesn't have headers, each row will be converted to a simple array of values.
You can customize the delimiter used in your CSV data (comma, semicolon, tab, or pipe) and choose whether the first row contains headers. The tool also allows you to set the indentation level for the output JSON.
