Frequently Asked Questions
What is CSV?
CSV (Comma-Separated Values) is a plain text format for storing tabular data. Each line is a row, and fields are separated by commas. CSV is widely used for data import/export in spreadsheets, databases, and APIs.
How does the CSV to JSON converter work?
When "First row is headers" is checked, the first row becomes the JSON keys and subsequent rows become values. For example, a CSV with headers "name,age" and a row "John,30" becomes {"name":"John","age":"30"}. Without headers, values are placed in arrays.
Does it handle quoted fields?
Yes, the converter properly handles fields wrapped in double quotes, including fields containing commas, newlines, or escaped quotes. For example: "San Francisco, CA" is treated as a single field.
What delimiters are supported?
Comma (default), semicolon, tab, and pipe. Semicolon is commonly used in European locales where the comma is the decimal separator. Select the appropriate delimiter from the dropdown.
Is this tool free?
Yes, completely free with no sign-up required. All conversion happens in your browser โ your data is never uploaded.
