TSV CSV Viewer

Lightweight Browser-Based Table Viewer

When working with tabular text data, a plain text editor often makes it hard to see column boundaries clearly, and launching a full spreadsheet application can feel like overkill. This tool is a lightweight viewer that renders TSV and CSV data as an HTML table directly in your browser, with automatic row and column counting.

Easy to Use

You can paste data into the text area or drag and drop a file. The delimiter auto-detection feature means you do not need to worry about whether the data uses tabs or commas. You can also toggle whether the first row should be treated as a header, which is helpful for headerless datasets. An optional row number display helps you quickly locate and reference specific rows.

Privacy and Security First

No data is sent to any server and all processing happens locally in the browser, so you can safely inspect internal data or files containing personal information. Supports files up to 10 MB in size. It is well suited for everyday data verification, log inspection, content checks before sharing files, and quick debugging of data structure.
