FAQ
What delimiters are supported?
Four common delimiters are supported: comma (,), tab, semicolon (;), and pipe (|). Choose the appropriate one based on your CSV data format.
How to handle fields containing commas?
If a CSV field contains the delimiter (such as a comma), the field should be enclosed in double quotes. This tool correctly parses quoted fields, including line breaks within quotes.
What does 'Use first row as header' mean?
When this option is checked, the first row of the CSV will be used as the field names (keys) in the JSON objects. If unchecked, all rows will be output as an array of string arrays.
