Frequently Asked Questions
What is CSV format?
CSV (Comma-Separated Values) is a plain text format for storing tabular data. Each line represents a row, and values within each row are separated by commas. It's commonly used for data export from spreadsheet applications like Excel and Google Sheets.
How does the converter handle headers?
When "First row contains headers" is checked, the first row of your CSV is used as property names in the JSON objects. If unchecked, the tool will generate generic property names like "column1", "column2", etc.
Can I convert CSV files with commas in the data?
Yes, if your CSV data contains commas within fields, make sure those fields are enclosed in double quotes (e.g., "New York, NY"). The parser will correctly handle quoted values containing commas.
Is my CSV data sent to a server?
No. All CSV to JSON conversion happens locally in your browser using JavaScript. Your data never leaves your device and is not stored or transmitted anywhere.
What format is the output JSON?
The output is an array of JSON objects, where each object represents one row from your CSV. Each object's properties correspond to the CSV columns, with values properly parsed and formatted.
