Does it handle CSVs with quoted values containing commas?

Yes, properly quoted fields (where a comma inside a value is wrapped in quotes) are parsed correctly rather than treated as an extra column.

Can it display large CSV files?

Yes, though very large files (tens of thousands of rows) may take a moment to render as a table.

Does it support delimiters other than commas?

It's built around standard comma-separated files — for tab, semicolon or pipe-delimited files, convert first with the CSV Delimiter Converter.

Does CSV Viewer upload my files to a server?

No. CSV Viewer runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

A CSV file is just plain text with commas separating values — open it in a basic text editor and you get a wall of unaligned text that's genuinely hard to read once a row has more than a few columns. This tool renders a CSV as a properly formatted table with aligned columns and rows, making it readable at a glance the way a spreadsheet would, without needing spreadsheet software installed or uploading the data anywhere.
