Pro: import and export

In Redirects > Settings > Import and export choose a CSV file and click Import. The columns are:

1. source: the old address (required).
2. target: the new address (empty only for 410).
3. code: 301, 302, 307 or 410. Empty means 301.
4. regex: 1 if the old address is a regular expression.

A first row with the column names is skipped. Comma and semicolon both work, so a file saved by Excel in any language is fine. Addresses already in the list are skipped; lines with errors are listed after the import, the first five with the reason.

Export CSV in the list of redirects downloads all of them in the same format, ready to import on another site.
