Does CSV to JSON converter infer data types?

Yes. Numbers remain numbers, true/false values become JSON booleans, and empty cells become null. String values are preserved as strings.

Does it handle commas inside quoted CSV fields?

Yes. Quoted fields (e.g. "Smith, John") are treated as a single value, and the comma inside is not treated as a delimiter.

Frequently Asked Questions

Does the converter infer data types?

Yes. Numbers stay as numbers, true/false become booleans, and empty cells become null. Everything else is treated as a string.

What if my CSV has commas inside fields?

Quoted fields are handled correctly. A value like "Smith, John" is treated as a single string and the inner comma is not used as a delimiter.

Does it need a header row?

Yes. The first row is used as the keys for each JSON object. Make sure your CSV has descriptive column headers for clean output.

Can I use this for spreadsheet exports?

Yes. Export your spreadsheet as CSV from Excel, Google Sheets, or Numbers, paste it here, and get a JSON array you can use directly in your app.

Is the tool free?
