Frequently Asked Questions
How are CSV headers used?
The first row of your CSV is treated as column headers. These become the property keys in each JSON object. Make sure your headers are descriptive and unique.
Are numbers preserved as numbers?
Yes, the converter detects numeric values and outputs them as JSON numbers (without quotes), enabling accurate calculations in JavaScript.
What's the difference between JSON and JSONL?
This converter outputs a standard JSON array. For JSON Lines format (one object per line), use our CSV to JSONL converter.
