How to clean up artifacts out of commit history

We have put files into the commit history that we do not need to keep. For example, a json, csv, or xslx file that is unnecessary. Therefore, we should use BFG to clean up the repo:

Steps to take: brew install openjdk
download BFG

prune local branches with git remote prune origin if needed, so that your branches that don't exist on origin stop carrying the baggage forward

If that doesn't work, then we can try:

cd /tmp

git clone --mirror <ironbank-tools repo>

java -jar ~/Downloads/bfg-1.13.1.jar --delete-files *.xlsx ironbank-tools.git
