CSV to JSON

Convert CSV rows into a JSON array.

When to use this tool

Use this tool when you need to transform tabular CSV data into structured JSON for API payloads, configuration files, or further programmatic processing. It is useful for migrating spreadsheet data into JavaScript, Python, or other JSON-native environments.

How to use

Paste your CSV content (first row should be headers) into the input area and click Convert. The tool outputs a JSON array of objects where each object key is the column header and each value is the corresponding cell value.

How this works


					

				
How this works

				

											
The first CSV row is treated as the header row, and each following row becomes one JSON object.

											
Column names become object keys. Cell values stay as strings so the conversion does not guess incorrectly about IDs, postal codes, or formatted numbers.

									

			

		
					

				
Examples

				

											

															
Two-column CSV

							
							

								

									
Input

									
name,age
Jane,31

								

								

									
Output

									
[
  {
    "name": "Jane",
    "age": "31"
  }
]

								

							


															
The age value remains a string because CSV has no native number type.

													

											

															
Quoted comma

							
							

								

									
Input

									
name,city
"Jane Doe","Porto, Portugal"

								

								

									
Output

									
[
  {
    "name": "Jane Doe",
    "city": "Porto, Portugal"
  }
]

								

							


															
Quoted values can contain commas without creating extra columns.

													

									

			

		
					

				
Edge cases to know

				
    
											
  • The CSV must include headers and at least one data row.
    • 
											
  • Duplicate headers can overwrite values when converted to JSON object keys.
    • 
											
  • Quoted multiline fields depend on valid CSV escaping and may not match every spreadsheet export style.
