CSV Viewer: free online, fast and secure
Not everyone has Excel, and phones show CSV files as messy text. This viewer opens CSV files as a clean table where you can sort by any column and search across all rows.
Separators are detected automatically, and you can export the filtered rows as a new CSV.
How to use CSV Viewer
- Open a CSV. Choose a file or paste CSV text.
- Sort and search. Click column headers to sort; type to filter rows.
- Export. Download the filtered rows as CSV.

Good to know
Most data problems come from small format differences: a semicolon instead of a comma, a missing header, text encoded incorrectly, or dates in different styles. CSV Viewer handles these details automatically, including UTF-8 encoding so Hindi and other Indian languages display correctly, and it shows a preview so you can check the result before downloading.

How CSV Viewer keeps your documents and data files private
When you add a file to CSV Viewer, it is opened with your browser’s own engine, processed in memory and offered back to you as a download. ConvertKaro never receives a copy. This is why the tool is fast even on 4G, why there is no daily limit, and why it is safe for confidential documents and data files like ID proofs, bank documents, contracts and family photos.
