Gists This is a script for modifying the shading color of paragraph on Google Document using Google Apps Script. Recently, by releasing Google Docs API, the shading color got to be able to be modified using the script. Here, I would like to introduce a sample script for modifying the shading color of the paragraph on Google Document. At the current Document Service, the shading color cannot be modified yet. I think that this will be achieved in the future update.
