$ cat FAQ.md
What file formats are supported?▶
The viewer supports CSV (comma-separated), TSV (tab-separated), and other delimited text files. The delimiter is auto-detected. You can also paste data directly.
Is my file uploaded to a server?▶
No. The file is read and parsed entirely in your browser using PapaParse. Your data never leaves your device.
How does sorting work?▶
Click any column header to sort by that column. Click again to reverse the sort order. The tool auto-detects numeric columns and sorts them numerically rather than alphabetically.
Can I search and filter the data?▶
Yes. Use the search box to filter rows. It searches across all columns and shows only rows that contain the search text. The row count updates to show filtered vs total rows.
