Frequently Asked Questions

Is my data safe?
Absolutely. CSVArc processes everything in your browser using JavaScript. Your files are never uploaded to any server — they stay on your device.
How large a file can I view?
CSVArc uses virtual scrolling to handle files with 100,000+ rows without freezing your browser. The practical limit depends on your device memory.
What file formats are supported?
CSV, TSV, and plain text files with delimited data. The delimiter is auto-detected (comma, semicolon, tab, or pipe).
Can I sort and filter the data?
Yes. Click any column header to sort (ascending, descending, or none). Use the filter inputs below headers to narrow down rows.
