@kmika11 thanks for the pull request! I see you used the develop branch. Would it be possible for you to make another PR from a different branch? You could call it "10339-workflow` or whatever. It will make it easier to review and add commits later, per this issue:

• Document how to update a "develop branch to develop branch" pull request  #9508

Also, I see a lot of whitespace changes. Maybe we can check with @jggautier on what he does but originally we would edit in google spreadsheets and download a .tsv from there. You should be able to use https://docs.google.com/spreadsheets/d/13HP-jI_cwLDHBetn9UKTREPJ_F4iHdAvhjmlvmYdSSw/edit#gid=447508596 as a starting point, I would think. I hope!

I'm not sure if that works, but worth a try. I don't remember what I usually do, but I've run into this issue with whitespace changes too when the application I'm using to open the tsv files, like excel, adds extra tabs so that each row has the same number of columns.
