Frequently Asked Questions

CSV (Comma-Separated Values) is a simple text format for storing tabular data. Each line represents a row, and values within a row are separated by commas (or other delimiters). CSV files are widely used for data exchange between applications like spreadsheets and databases.

Absolutely! All file processing happens directly in your web browser using JavaScript. Your CSV files are never uploaded to any server, ensuring complete privacy. The viewer even works offline once the page is loaded.

The viewer supports .csv, .tsv, and .txt files. It can automatically detect common delimiters including commas, semicolons, tabs, and pipes. You can also manually select a delimiter if auto-detection doesn't work for your file.

The viewer supports files up to 10MB. For very large files with many rows, use the row limit setting to display a subset of data for better performance. You can still export all data regardless of display limits.

This is a read-only viewer designed for previewing and exporting CSV data. For editing, we recommend using spreadsheet software like Microsoft Excel, Google Sheets, or LibreOffice Calc.
