Batch rename using text file for new name

Hello,
I am batch exporting file names and I have no control over the output name of each file. I need to rename each file name to a specific Name. I have created a text or xls file that has the exported (original) file name in one column and the file name should be renamed to (new name) in another column.
Is there a way to use the text file to lookup the old name and rename it to the new name?

I have used CSV import.

Tried changing names from:

original file names: to new file names:
apple Tiger
orange Cat
pineapple Snake
apple Tiger
Lemon Deer


but while loading csv file the status says "cannot find source file"

Please help

Reply to #2:
You need to set the "Base folder for original files" to the correct folder containing the files to be renamed. If you don't point it to the correct folder, the program won't be able to find the files and add them to the list.
