Frequently Asked Questions
What is a CSV file?
CSV (Comma-Separated Values) is a plain text file format used to store tabular data. Each line represents a row, and values are separated by delimiters (usually commas).
Which delimiters are supported?
The CSV Viewer supports three common delimiters: comma (,), semicolon (;), and tab (\\t). Choose the one that matches your CSV file format.
What if my CSV doesn't have headers?
Simply uncheck the "First row contains headers" option. The viewer will automatically generate column headers like "Column 1", "Column 2", etc.
Is there a file size limit?
The tool processes files entirely in your browser. Very large files (over 10MB) may take longer to load or cause performance issues depending on your device.
Is my data secure?
Yes! All processing happens entirely in your browser. Your CSV data never leaves your device and is not sent to any server.
