How does the CSV viewer work?
This tool parses your CSV in the browser using an RFC 4180-compliant parser that handles quoted fields, escaped quotes (""), and embedded newlines. The data is rendered as a sortable HTML table — click any column header to sort. Search filters across all columns. Auto-detect tries common delimiters (comma, tab, semicolon, pipe) and picks the one that produces the most consistent column count.
Common uses
- Quick CSV inspection — view files without opening Excel.
- Format validation — confirm a CSV parses correctly before importing.
- Data exploration — sort, search, and scan rows interactively.
- JSON conversion — copy or download the table as a JSON array of objects.
Privacy
All parsing runs 100% in your browser. Files never leave your device.
