What is a CSV file and why use a CSV viewer?

CSV (Comma-Separated Values) is a universal plain text format for tabular data where each line is a row and commas separate columns. CSV files are used for data exports from databases, spreadsheets, analytics tools, and CRM systems because they're simple, lightweight, and universally compatible. Our CSV viewer makes these files human-readable by rendering them as formatted tables with headers, aligned columns, and interactive controls instead of raw comma-separated text.

Is my CSV data safe and private?

Yes, absolutely. All CSV parsing, table rendering, sorting, filtering, and analysis happens entirely in your browser using client-side JavaScript. Your data never leaves your device - there are no server uploads, database storage, or external API calls. This makes our viewer perfect for confidential datasets, customer records, financial data, HR information, and any sensitive CSV files.

Can the viewer handle different delimiters (semicolons, tabs, pipes)?

Yes! Our CSV viewer automatically detects common delimiters including commas, semicolons (common in European Excel exports), tabs (TSV files), pipes, and custom separators. It also properly handles quoted fields with embedded delimiters, escaped quotes, and various CSV dialects from different systems for accurate parsing.

What's the maximum CSV file size supported?

The viewer supports CSV files up to 100MB. We use efficient streaming parsing and virtual scrolling to handle large datasets with millions of rows without browser crashes or performance issues. Large files are processed in chunks for smooth rendering and responsive interaction.

Can I sort and filter my CSV data?

Yes! Click any column header to sort ascending/descending with intelligent sorting (numbers sorted numerically, dates chronologically, text alphabetically). Use the search box to filter rows across all columns, finding specific values, customer names, IDs, or data patterns instantly. All filtering and sorting is fast even with large datasets.

Does the viewer work with CSV exports from Excel and Google Sheets?

Yes, perfectly! The viewer handles CSV exports from Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications. It correctly parses quoted fields, handles various encoding formats (UTF-8, Windows-1252, ISO-8859-1), and preserves special characters, currencies, and international text.

Can I view CSV files on mobile devices?

Yes! The CSV viewer is fully responsive and mobile-optimized. Tables adapt to smaller screens with horizontal scrolling, touch-friendly column resizing, and mobile-optimized controls. View CSV exports on phones and tablets with smooth scrolling and touch gestures for data analysis on the go.

Can I copy or export data from the viewer?

Yes! Copy individual cells, select and copy entire rows/columns, or export filtered results back to CSV format. Data can be pasted into Excel, Google Sheets, text editors, or other applications. Use export options to download modified datasets or filtered results for further processing.
