Exporting data from Excel or Google Sheets as CSV and then converting to JSON is one of the most common data pipeline steps in marketing, operations, and analytics. Our converter handles the most common CSV quirks: quoted fields with commas inside, trailing newlines, BOM characters, and both Windows (CRLF) and Unix (LF) line endings. The first row is treated as headers, creating clean key-value pairs ideal for REST API payloads, product catalog imports, or database seeding scripts.
