CSV to JSON: Turn Spreadsheet Rows Into Objects in Seconds
Spreadsheets love rows and columns, while apps love objects. This converter bridges the gap without a spreadsheet export dance.
What is the CSV to JSON Converter?
Paste a CSV table and get a JSON array where each row becomes an object keyed by the header row. The parser respects quoted fields, so commas inside quotes stay part of the value instead of splitting a column. It is handy when moving data from a spreadsheet into an app, an API test, or a config file.
How to use it
- Paste your CSV, keeping the header row at the top.
- Check that quoted fields keep their commas inside the quotes.
- Click Convert to JSON.
- Copy the pretty JSON output for your app or file.
Worked example
Converting name,age / Ada,36 / Grace,40 gives a JSON array with objects for Ada and Grace.
How do I turn a CSV table into JSON?
Paste the CSV with its header row first, then convert. Each later row becomes one JSON object, with header names as keys and row cells as values.
Frequently asked questions
Does it handle commas inside quoted fields?
Yes. A comma inside double quotes is treated as part of the value, not a column separator.
What if a row has fewer columns than the header?
Missing values are filled with an empty string so every object has the same keys.
