Frequently Asked Questions (FAQ)

How do I open a CSV file without Excel?

With our free tool, you can open, view, and edit CSV files directly in your web browser. There is no need to install software like Microsoft Excel. Simply drag and drop your file into the designated area on the homepage.

Is it safe to view CSV files online?

Yes, absolutely. Unlike many other online converters, CSV Viewer & Exporter processes all data locally. We use your browser's native FileReader API. Your files are never uploaded to our servers, guaranteeing 100% privacy and GDPR compliance by design.

Which file formats are supported?

We currently support:

• .csv (Comma-Separated Values, including semicolon or tab delimiters)
• .xlsx (Modern Excel files)
• .xls (Legacy Excel files)
• .xlsm (Excel files with macros – however, macros are not executed)

Why are some characters or delimiters displayed incorrectly?

Our tool attempts to detect the delimiter automatically (e.g., comma or semicolon). If a program like Mac Numbers exports a file with unusual formatting, our parser usually handles it smoothly. For best results, ensure your file is encoded in UTF-8.
