Google Sheets Form Validation Script

@kamran2012

Interesting project, I will build the Apps Script with an onFormSubmit trigger that validates required columns, moves incomplete rows to a "Rejected" sheet, and notifies submitters via toast or email — plus well-commented code so you can edit the required-field list in one array. One thing worth adding: a timestamp and reason log on rejected rows so you can track which fields fail most and refine your form accordingly. Questions: 1) How many columns need validation, and are any conditional — e.g., field B required only if field A has a specific value? 2) Should incomplete submissions trigger an email back to the respondent, a toast for editors, or both? Looking forward to potentially working together. Thanks, Kamran

Hello, I’ve gone through your project details and this is something I can definitely help you with. I have 10+ years of experience in mobile and web app development, working with various technologies including Google Apps Script. My focus on clean architecture and clear communication ensures a smooth project flow from start to finish. I will create a lightweight Apps Script bound to your Google Sheet that triggers on Form Submit. This script will inspect incoming data against your specified required fields and alert users with a friendly toast pop-up or email if any necessary information is missing. I’ll include clear comments in the code, making it easy for you to adjust the required fields later. Additionally, I'll provide a brief hand-off note or Loom video to guide you through enabling the trigger and testing the validation. Here is my portfolio: https://www.freelancer.in/u/ixorawebmob I’m interested in your project and would love to understand more details to ensure the best approach. Could you clarify: 1. What specific fields do you consider "required"? Let’s discuss over chat! Regards, Arpit Jaiswal

Your form validation will fail the moment someone submits partial data through a shared link or API call that bypasses the native Google Form constraints. Apps Script triggers fire after the row is written, so you're not actually preventing bad data from landing in the sheet - you're cleaning up after the fact. Before I write the validation logic, I need clarity on two things: Are you using a native Google Form feeding into this sheet, or are users submitting data through a custom web app or third-party integration? And when you say "stop any row," do you mean delete it immediately, move it to a quarantine tab, or flag it in place? The architecture changes completely depending on your answer. Here's the validation approach: - GOOGLE APPS SCRIPT + ONFORMSUBMIT TRIGGER: Build an event-driven validator that fires on new submissions, checks your required columns (A, C, E - whatever you specify), and routes incomplete rows to a separate "Pending Review" sheet while sending the submitter an automated email with missing field details. - CUSTOM PROPERTIES SERVICE: Store your required-field configuration in script properties so you can update the validation rules through a simple settings menu without touching code. I'll add a custom menu bar with "Update Required Fields" and "Test Validation" buttons. - ROLLBACK MECHANISM: Implement version history snapshots using a hidden audit log that timestamps every validation action, so you can restore deleted rows if the script misfires during testing. I've built similar validation layers for 4 clients processing 500+ daily form submissions, including one healthcare intake system that had to enforce HIPAA-compliant field requirements before routing patient data. The script I'll deliver includes inline comments explaining every conditional check and a 5-minute Loom walkthrough showing trigger setup, test scenarios with intentionally incomplete data, and how to adjust the required-field array. Let's jump on a quick call to confirm your data flow and whether you need the rejected rows archived or permanently blocked - I don't start coding until the edge cases are mapped out.

Hey, I’ve reviewed your project and see you need a lightweight Google Apps Script that validates incoming Google Form responses in real time and prevents incomplete rows from being accepted into your main sheet. I can build a clean, efficient script that triggers on form submission, checks your defined required columns, and immediately flags or rejects incomplete entries. The script will be fully commented so you can easily update the required fields list without digging into the logic. It will either show a user friendly toast notification or send an email alert (depending on your preference), ensuring users are informed instantly when something is missing. I’ll also make sure the flow is optimized so it doesn’t slow down your sheet or interfere with incoming data processing. I’ve built similar validation and automation scripts in Google Apps Script for form-driven workflows and understand how to keep them simple, reliable, and easy to maintain. You’ll also get a short handover guide or Loom walkthrough showing setup, trigger configuration, testing steps, and rollback options. Let’s connect and I can set this up quickly for you.

Hello, This is a perfect use case for a clean Google Apps Script automation, and I can set this up so every new form submission is validated instantly before it’s accepted as complete. I’ll create a script bound to your Google Sheet that triggers on form submit and checks the required columns you define. If any required field is missing, the script will: • Flag the row clearly (so it doesn’t get treated as valid data) • Send a friendly email notification to the respondent (or admin) • Optionally show a toast notification for visibility inside the sheet The code will be well-structured and commented, making it easy for you to update the list of required fields later without digging into complex logic. I’ll also ensure: • Clean trigger setup (onFormSubmit) • Safe handling so existing data isn’t affected • Easy rollback or disable option if needed You’ll receive a short hand-off guide (or Loom walkthrough) showing: • How to enable/disable the trigger • How to edit required fields • How to test the validation flow I’ve implemented similar validation layers for Google Forms + Sheets workflows, ensuring clean and reliable data capture. I can get this done quickly and keep it lightweight and maintainable. Best regards
