Frequently Asked Questions
How does the converter identify JSON property keys?
The first line of your CSV is treated as the header row. Each column header becomes the property key for every subsequent record row.
Does this parser handle commas inside quoted text?
Yes. The parser recognizes double-quoted fields (e.g., "San Francisco, CA") and treats the enclosed comma as text rather than a column delimiter.
Can I paste data directly from Excel or Google Sheets?
Yes. Simply select your table in Excel or Google Sheets, copy it, and paste it into the editor. Comma- and tab-delimited values are handled cleanly.
Is my CSV business data safe and private?
Yes. All parsing and JSON generation occurs entirely within your browser's local memory. Your records, customer information, and financial data are never uploaded to any server.
