What CSV formats does the viewer support?

The viewer supports standard CSV files following RFC 4180, including quoted fields, embedded commas within quoted fields, escaped double-quotes, and multi-line values. It handles files with any number of columns and rows, and automatically detects the delimiter.

Can I view large CSV files?

Yes. The viewer renders large CSV files efficiently in the browser. Files with tens of thousands of rows load and scroll smoothly. Performance depends on your device, but the viewer handles significantly larger files than Excel without freezing.

Does the viewer change my CSV data?

No. Unlike Excel, which auto-converts numbers, strips leading zeros, and reformats dates, the viewer displays your data exactly as it appears in the CSV. Values are never modified or reformatted.

Can I sort and filter the data?

Yes. Click any column header to sort ascending or descending. Use the search box to filter rows by keyword. The export function includes only the currently visible rows after filtering.

Is my data uploaded to a server?

No. All processing happens locally in your browser. Your CSV data is never uploaded to any server, which makes the viewer safe for sensitive data like financial records, customer lists, and personal information.
