Frequently Asked Questions
What file formats are supported?
We support CSV (comma-separated), TSV (tab-separated), and Excel XLSX files. Old XLS format is not fully supported - please save as XLSX or CSV.
Can I edit the data?
This is a viewer tool focused on reading and analyzing data. For editing, you can export to CSV and use a spreadsheet application, or use our CSV to JSON converter.
How are data types detected?
We analyze column values to detect numbers, dates, booleans, and text. This helps with proper sorting and display formatting.
Is there a file size limit?
Files are processed entirely in your browser. Very large files (>50MB) may be slow to load depending on your device. For best performance, keep files under 10MB.
