Very little coding experience required
validate google form entries with google sheets
If you are looking for a way to validate a string submission in google forms using Google SpreadSheets as your "database," this is a good place to start. This script will compare a form submission to a google sheet and email the user whether their submission was valid or invalid, even if their response has capitals or spaces before or after the word.
To use:
- Create, name and save your Google Spreadsheet. Get column headers set up for ease of use
 - Create, name and save your Google Form. Complete setup of form for ease of use
 - Click triple dots on upper right hand corner and select "script editor"
 - Copy and paste the code in code.gs
 - Set filename of Sheet - No key necessary!
 - Set variables to match form and sheets
 - Use CapitalizeFirstLetter as needed for proper nouns in email
 - Set validator to check correct field and column
 - Change params in SendEmail as needed
 - Write your HTML email
 - TEST!
 
I am planning on creating a plugin verison of this eventually. Enjoy!
