Question 1

How does the View Any File CSV Viewer & Opener work?

Accepted Answer

This tool uses a JavaScript library (SheetJS) to parse .csv files directly in your browser. It then displays the data as an HTML table. Standard comma-separated values are expected.

Question 2

Is my uploaded .csv file secure?

Accepted Answer

Yes. File processing happens entirely within your web browser. Your data is not uploaded to any external server, ensuring your privacy.

Question 3

Does it support different delimiters (e.g., semicolons, tabs)?

Accepted Answer

This viewer primarily expects comma-separated values. While SheetJS has some auto-detection capabilities, files with unusual delimiters might not parse correctly. For best results, ensure your CSV uses commas as delimiters. For tab-separated files, please use our TSV Viewer (link to /viewer/tsv).

Question 4

Are there limitations on CSV file size?

Accepted Answer

Very large CSV files might take longer to process and render in the browser. Performance depends on your browser's capabilities and the size of the file.

Question 5

Can I view Excel files (.xlsx, .xls) here?

Accepted Answer

This page is specifically optimized for .csv files. For Excel files, please use our dedicated XLSX Viewer (link to /viewer/xlsx) or XLS Viewer (link to /viewer/xls).
