I know there is an align/distribute feature in Kicad. I don't use it much, though. Is it different from what you expected? How did you install Kicad?
Actually, text-editing kicad files is a thing. I have done it, and you can save a lot of work, using a good text editor with regex search.
Please always keep safe a version which has not been edited via text-editor.
You'll be interested in regexr.com, where you can test and learn using regex to make clever edits.
