git filter details, see https://git-scm.com/book/en/v2/Customizing-Git-Git-Attributes

Setup Steps:

Add keyfilter.py

1. copy keyfilter.py into your project
2. to avoid committed keyfilter.py, add it into .gitignore

Add Git Attributes

1. Add .gitattributes in your workspace, and add content as below

configData.json    filter=keyfilter

2. Or edit .git/info/attributes if you don’t want the attributes file committed with your project

echo 'configData.json    filter=keyfilter' >> .git/info/attributes

Add Git Config Filter

1. Add by command and it will add in .git/config, which will not be committed with your project

git config filter.keyfilter.smudge "python keyfilter.py --smudge"
git config filter.keyfilter.clean "python keyfilter.py --clean"

2. Or edit .git/config, which will not be committed with your project

[filter "keyfilter"]
        smudge = python keyfilter.py --smudge
        clean = python keyfilter.py --clean

3. Or add .gitconfig as local, which will be committed with your project. and add content in last step

git config --local include.path ../.gitconfig

Note:

1. Avoid to use simple keywords, which may conflict with replace content, for example:

{
    "username": "user"
    "password": "pass"
}
