CSV to JSON Converter

Turn CSV rows into JSON arrays with optional headers and pretty formatting.

Convert Data

Examples

JSON Input (Array of Objects):

[
  {"name": "John Doe", "age": 30, "city": "New York"},
  {"name": "Jane Smith", "age": 25, "city": "London"}
]

CSV Output:

name,age,city
John Doe,30,New York
Jane Smith,25,London

What It Does

CSV to JSON Converter turns CSV rows into a JSON array of objects. It supports headers or auto-generated column names, custom delimiters, quote handling, and optional pretty-printed output for easy debugging.

Key Features:

  • Parses CSV with headers or auto column names
  • Handles quoted fields, commas, and escaped quotes
  • Custom delimiter support (comma, semicolon, tab, or custom)
  • Pretty-print JSON output option
  • Trims empty lines to avoid stray objects

How To Use

Paste CSV text and convert it into a JSON array ready for APIs or scripts.

1

Paste CSV

Include a header row if you want meaningful keys (e.g., name,age,city). Without headers, generic keys like col1 are used.

2

Choose Delimiter

Select comma, semicolon, tab, or a custom character to split columns.

3

Set Header Mode

Toggle whether the first row is treated as headers.

4

Convert

Convert to see a JSON array; enable pretty print for easier reading.

Pro Tips

  • •Keep header names simple; they become JSON keys
  • •If your CSV uses semicolons (common in EU locales), set the delimiter accordingly
  • •Quoted fields with commas are handled automatically
  • •Blank lines are skipped to prevent empty objects

Frequently Asked Questions

1 What if there is no header row?
The converter generates generic column names (col1, col2, …). Provide headers for clearer JSON keys.
2 How are quotes handled?
Quoted cells keep embedded commas and escaped quotes are unescaped, following standard CSV rules.
3 Can I change indentation?
Enable or disable pretty print to switch between compact and indented JSON output.
