Add last number string of tittle to keywords

[mastix]

I have images named:  historicalimage-net 1 , historicalimage-net 2 , historicalimage-net 3. I would like to pull automatically with an action the number after the "net" and include that number as a keyword in the IPTC/XMP data. How would you approach this problem. I have various plugins in Lightroom for rename like Search+ replace etc but with none can I solve this problem.

Thank you

One method: You could export the file names to a CSV file using the LR/Transporter plugin. Then use a text editor with regular-expression capabilities to add a Keyword column to the file containing the numbers at the ends of the file names.  Use the LR/Transporter plugin to import that CSV and add keywords corresponding to the Keyword column.

Thank you. I found finally an easy way inside Lightroom, using the Lightroom plugin Search and replace . It requires a few steps, but I am much more comfortable to do it with a plugin that with CSV or Excel files that I am not proficient working with. I am learning do , so I might try your method in the future

Thank you in any case for your input.
