Create a Google Doc for each submission of a Google Form and translate some of that Form data into the Doc. It puts a link to the newly created Google Doc back into the spreadsheet alongside the relevant row. The Name field from the Form is used as part of the filename for the created Doc and there is a Log sheet to support any troubleshooting errors.
I use Google Apps Script to support staff and students in my job. I enjoy dabbling with creating tools to help with automation and I freely share my learning experiences on my blog, where I also have a number of useful Google Add-ons: www.pbainbridge.co.uk
