How to use CSV to JSON
Create a JSON array from a comma-separated table with a header row. Each following row becomes an object whose keys are the column names. Quoted commas and line breaks are supported. Values remain strings, so numeric and boolean conversion must be handled separately if your application requires it.
01
Paste the CSV table
Include a header row and at least one data row.
02
Convert rows to objects
Generate JSON using the first row as the object keys.
03
Review and save JSON
Check the string values and download the JSON output.
COMMON QUESTIONS
CSV to JSON: useful answers
Are numbers converted to numeric JSON values?
No. All CSV field values remain strings, including numbers, dates, and values such as true or false.
Can header names be blank or repeated?
No. Column names must be non-empty and unique, and each data row must have the same number of columns as the header.
