About CSV to JSON Converter
This CSV to JSON converter turns rows of comma-separated text into a JSON array. If the first row is a header, each record becomes an object keyed by the header names; otherwise you get plain arrays of values.
CSV looks simple until a value contains the delimiter itself. The standard fix is to wrap that value in double quotes and double up any internal quote, and this converter follows those rules instead of just splitting on commas, so a field like "Loves ""puzzles"" and notes" comes through intact.
Use it when you need to turn a spreadsheet export into data your code or API can consume. Switch the delimiter to semicolon or tab if that is what your source file uses before converting.
Frequently asked questions
- Does it handle commas inside values?
- Yes, as long as the value is wrapped in double quotes, which is the standard CSV convention.
- Can I convert a semicolon- or tab-separated file?
- Yes, choose the delimiter above the input box before pressing Convert.
- Is my data uploaded anywhere?
- No, the conversion runs entirely in your browser.
- What happens if a row doesn't match the header length?
- Missing values become empty strings, and the output still keys each field to its header.
