Rename Files using csv list / excel file (exported to CSV)
If you execute the script in the same directory as the files, you don't have to add the full path, but if it's in a different directory the the full path is needed
You can start with an excel file. Header has to be Path and NewName Then export the file as CSV
| Path | NewName |
|---|---|
| cat.jpg | cat01.jpg |
| dog.jpg | dog02.jpg |
| rat.jpg | rat03.jpg |
Path refers to the Old Filename and NewName is the New Filename
The reason why we add the Path, and NewName is because the Rename-Item function accepts a Path string and a NewName string
import-csv ./rename.csv | rename-item
The CSV File
Path,NewName dog.jpg,222-dog.jpg rat.jpg,333-rat.jpg cat.jpg,111-cat.jpg
