Export all images from a Word (.doc) document .. and rename them

· July 29, 2013

During the summer I was handed a delicate task for the book: “… and also, if you could hand us all the images in the book, thank you very much. Oh yeah, if you could name them CH01_01.png, CH01_02.png etc it would be great.”

Yes I felt a bit like:

Since Kanban In Action now have 13 chapters in different .doc-files I immediately realized two things: - Marcus - your are stupid for not tracking these images somewhere - This is to big to do manually This post describes how I did. It took me about 2 hours all together. ### Export all files in a Word document The chapters are written in .doc formats (for some reason), but I seem to recall that the newer format .docx in reality is just a zip-file. Maybe, just maybe, that could help me. 1. I "Save as..."'ed the file to .docx. 2. Then I renamed the file to .zip and extracted the archive to a folder. 3. Low and behold; in the \[Name of your word document\]/word/media-folder all the images were listed. In the order they appeared in the document. The only downside, if you could call it that, was that the files were named: image1.png, image2.png etc. That was the task up next: ### Renaming a lot of files (on OSX) I now had all the files from all the documents, in separate folders. That amounted to about 300 pictures. Yeah - Kanban in Action is graphic-heavy! 300 pictures is way more than I care to rename by hand. Remember that they wanted each file to be named \[chapter number\]\_\[sequence number in chapter\].png. I then found this awesome video that shows how to do that with Automator. Here are the steps I ended up using: 1. Start Automator 2. Choose New-\>Application 3. Search for "Rename Finder Items" and click OK 4. Select "Don't add" in the dialog that ask you if you want to create copies of the file. I didn't since I wanted to rename them 5. In the drop down select "Replace text" and do your replacement settings. Here are my example:
6. Save the application to a wellknown place, for example the desktop. You have now created a little renamer application. To it you can drag the files you want to rename and ... presto - they will be ranamed.
