ASD's ROTE

Upload a CSV, choose one or more site columns, and I will check whether each site is reachable. All original columns are preserved, and new columns (for example, is_live, http_status, response_time_ms, resolved_ips) are appended.

Upload CSV

The app preserves all columns. By default it looks for a site column, but you can specify others below.

Site Columns (comma-separated)

Example: site, domain, host, url. Full URLs or bare hostnames work.

Path (optional)

If the input is only a hostname, the checker will request this path. If the input includes a path already, that path is used.

CSV Tips

Prefer UTF-8 CSV with headers.
Put hostnames in a column named “site,” or specify custom column names above.
Both example.com and https://example.com/foo are supported.
For large datasets, use CSV or Excel output instead of the on-page table.
