# CSV Viewer

View, search, sort, and filter CSV files online. No upload required — all data stays in your browser. Supports CSV, TSV, and TXT.

**Use this tool:** [CSV Viewer](https://findutils.com/convert/csv-viewer/)

## Programmatic access

- Browser-only: this tool works on a file, the DOM, or a browser API and has no REST or MCP id.

## Why Use CSV Viewer?

Our CSV Viewer lets you quickly inspect and analyze CSV data without installing any software. Search across all columns, sort by any column, and filter results instantly. Perfect for previewing data before importing or verifying exports from databases and applications.

## Tips for Working with CSV Files

- Always verify the delimiter before loading your file. A mismatched delimiter will cause all data to appear in a single column.
- Use the search feature to quickly locate specific rows instead of scrolling through thousands of entries manually.
- Click column headers to sort data numerically or alphabetically. This is especially useful for finding the largest or smallest values in a dataset.
- Export your filtered results as a new CSV file to create a clean subset of data without editing the original file.
- For very large files, consider splitting them first or using the CSV Column Extractor to remove columns you do not need before viewing.

## Frequently Asked Questions

### Is my data secure?

Yes! All processing happens locally in your browser. Your CSV file is never uploaded to any server.

### Can I search within the data?

Yes, use the search box to filter rows. The search looks across all columns and updates results in real-time.

### How do I sort the data?

Click on any column header to sort by that column. Click again to toggle between ascending and descending order.

### Can I export filtered results?

Yes, click the Export CSV button to download the currently filtered and sorted data as a new CSV file.

### What's the maximum file size?

There's no hard limit, but very large files (100MB+) may be slow to load depending on your device.

### What delimiters does the CSV Viewer support?

The viewer supports comma, semicolon, tab, and pipe delimiters. Select the correct delimiter from the dropdown before loading your file to ensure columns are parsed correctly.

### Can I open TSV or tab-separated files?

Yes. Drop your.tsv or.txt file into the viewer and select the Tab delimiter option. The viewer handles tab-separated values the same way it handles standard CSV files.

### Does the CSV Viewer work on mobile devices?

Yes. The viewer is fully responsive and works on phones and tablets. You can scroll horizontally through columns and use the search and sort features just like on desktop.

### Can I view CSV files with special characters or UTF-8 encoding?

Yes. The viewer correctly handles UTF-8 encoded files, including special characters, accented letters, and non-Latin scripts. Your data will display exactly as it was written.

### How do I convert my CSV to another format after viewing it?

After inspecting your data, use one of our conversion tools. Try CSV to JSON for API-ready data, CSV to Excel for spreadsheet editing, or JSON to CSV if you need to go the other direction.
