How to use the Google Apps Script Generator.
An Apps Script draft needs clear scope and permissions. Prefer a user-triggered operation for an initial version and avoid unnecessary access to other services.
Make the workflow fit your task.
Describe the sheet, exact range and desired change before drafting a function. Choose a manual trigger for an initial trial and explain which cells the script may alter. Run on a copy and compare the changed cells against a small known input.
- What you provide
- Sheet layout and bounded automation requirement.
- What you get
- Script draft with permissions and manual-run instructions.

Illustrative input and output · a teaching example, not a live WebAct run
Example input
Google Apps Script, bound to a spreadsheet. On sheet Intake, highlight blank cells in A2:B5 light red and reset nonblank cells to white. This explicit range contains required input cells only. Manual execution.
Completed example
function markMissingRequiredCells() {
const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Intake');
if (!sheet) throw new Error('Missing sheet: Intake');
const range = sheet.getRange('A2:B5');
const colors = range.getDisplayValues().map(row =>
row.map(value => value.trim() === '' ? '#fce8e6' : '#ffffff')
);
range.setBackgrounds(colors);
}
Only backgrounds in Intake!A2:B5 change; existing colors there are replaced. Test on a copy and review spreadsheet authorization. This example has not been executed in Apps Script.Load this input into the prompt, then copy it to WebAct to try the task. Your result may differ from the illustration.
Decisions and troubleshooting.
Should the script operate on whichever sheet happens to be active?
A named sheet and bounded range are easier to review. Use active-sheet behavior only when it is an intentional part of the task.
Why does the Apps Script request authorization?
Spreadsheet access can require permission. Review the script and requested scopes before authorizing, especially if additional services are referenced.
Reference for this workflow.
Try it with your own source.
Replace the example with your material in the task prompt. Keep the requirements you need, then copy the task into WebAct.
