Tiny Toolkit

CSV Viewer

Paste or upload a CSV file and instantly preview it as a clean, sortable table — no spreadsheet app required. Click any column header to sort ascending or descending. Useful for quickly inspecting exported data, checking row and column counts, and sanity-checking values before importing into a database or tool.

All processing happens in your browser. No data is sent to any server.

Frequently Asked Questions

What CSV formats does the viewer support?
It supports standard comma-delimited CSV with optional quoted fields. Semicolon-delimited files (common in European locales) are also auto-detected.
Can I sort the table by a column?
Yes — click any column header to sort that column ascending; click again to sort descending.
Is there a row limit?
The viewer handles a few thousand rows comfortably in the browser. Very large files may slow down rendering — consider splitting them first.
