Frequently Asked Questions
How does the tool handle commas inside quotes?
The parser complies with RFC 4180, ensuring text within quotation marks (such as "Seattle, WA") is treated as a single unified cell rather than an extra column delimiter.
What is column pad alignment?
Pad alignment pads every cell with trailing spaces so that all columns line up in vertical monospace columns, making plaintext CSV files instantly readable in text editors like VS Code and Notepad++.
Can I convert CSV directly to JSON?
Yes. Select "JSON Array of Objects" in the Output Format dropdown to automatically generate an array of JSON objects using the first row as object keys.
