# Map Region Names — Import & Export
> Export a map's regions and bulk-add alternate names by re-importing the edited file.
Export the regions of a map, add alternate names in Excel, then re-import to attach
them in bulk. This helps a map match more spellings and local names. Find it on the
**Maps** screen (Data Provider → Maps).

## Export
Go to **Maps** and open the map you want to enrich.
Click **Export**. The file lists every region with any names it already has.
## Import (add alternate names)
In the **Add Alternate Names** column, type the new names. Separate multiple names
with a pipe `|`, a semicolon `;`, or a new line.
Do **not** change **GeoNameId** — it identifies the region.
Click **Import** and choose your file. A summary reports how many regions were
updated and lists any skipped rows.
