Use TXT for plain number lists

TXT is simple: one number per line. It is often the easiest format when no extra fields are required.

Use CSV for system imports

CSV keeps multiple columns while staying widely compatible with spreadsheets, CRMs, and other data tools.

Use Excel for multi-field reports

Excel is useful when humans need to review fields such as city, carrier, or recognition status.

Check permission and limits before export

Trial, Advanced, and Top access can have different export quantities and fields.
