I need a lightweight, browser-based input page that lets anyone submit scaning and instantly records each entry in a specific Google Sheet. No login or user authentication is required—the form should be openly accessible through a simple link. Key behaviour • As soon as a user hits “Submit,” the text must appear on the next free row in the sheet. • Before committing the entry, the form should check the sheet for duplicates and alert the user if the same text already exists, preventing double posts. • Everything must work in real time; I don’t want to refresh the sheet manually to see new rows. Tech notes I’m comfortable with you using Google Apps Script, HTML/CSS/JavaScript, or any lightweight framework you prefer. If you like leveraging Claude or ChatGPT to speed up the build or generate validation logic, feel free—that’s actually a plus. The only requirement is that the final code be clean, documented, and easy for me to tweak later. Deliverables 1. Hosted forms (Google Apps Script web app, Firebase hosting, or similar—your call) 2. Connected Google Sheet with duplicate-check logic live 3. Source files and brief setup README so I can redeploy if needed Acceptance I’ll consider the job done when I can: • Open the link, submit a sample text, and see it land in my sheet within seconds. • Try to submit that same text again and receive a clear “duplicate” warning. That’s it—straightforward but important. Let me know your estimated turnaround and any questions.

Hi, I can upgrade this into a full Laravel-based system instead of Google Sheets, giving you a scalable and production-ready web application with real database storage, real-time updates, and duplicate validation. With strong experience in Laravel (10/11), MySQL, and real-time architecture, I can build a clean system that handles scanning input, instant record saving, and structured reporting—fully replacing your current Google Apps Script workflow. I will ensure the system is fast, modular, and easy to extend, so any future improvements or new features can be added without breaking the existing structure. Clean code, proper architecture, and maintainability will be my top priority.

I understand you need a lightweight, browser-based input page that allows users to submit data directly into a Google Sheet while ensuring no duplicates are recorded. This is essential for maintaining the integrity of your data without requiring user authentication. With over 12 years of experience in web development and automation, I can leverage Google Apps Script alongside HTML/CSS and JavaScript to create an efficient solution. The form will check for duplicate entries in real time, alerting users as needed without any manual refreshes on your end. I plan to host the form as a Google Apps Script web app for easy access and ensure the source code is clean and well-documented for your future modifications. Given your requirements, I estimate a turnaround of about 4-5 days to deliver everything, including a brief setup README. Could you clarify if there are any specific types of data or formats you expect users to submit? This will help ensure the form aligns perfectly with your needs.

Hi, I understand you need a lightweight browser-based form that instantly sends submitted scans/text into a Google Sheet while preventing duplicate entries in real time. I’ve worked with Google Apps Script and custom form integrations to build fast, reliable submission systems with live sheet updates and duplicate validation before data is stored. My approach would be to create a clean hosted form connected directly to your Google Sheet through Apps Script, where each submission is checked against existing rows before being added. If the text already exists, the user will immediately receive a duplicate warning without posting the entry again. The setup will be lightweight, easy to maintain, and fully documented so you can tweak or redeploy it anytime later. You’ll receive: • Hosted live form link • Google Sheet integration with instant updates • Duplicate-check logic • Clean source files + setup README I can deliver this quickly and make sure the workflow is smooth from submission to sheet update. One important question: should the duplicate check be case-sensitive, or should entries like “ABC123” and “abc123” be treated as the same value? Warm Regards, Junaid

Hello, I can build this as a lightweight, browser-based web app with a clean HTML/CSS/JavaScript front end and a secure Google Apps Script backend. With practical experience since 2018 as a Full Stack Developer, I focus on clean code, fast execution, and reliable data flow. For this project, I’d implement: - Open-access submission form with no authentication overhead - Real-time duplicate detection before insert - Atomic write flow to the next free Google Sheet row - Live Google Sheets integration using Apps Script or a minimal hosting setup - Clear, documented source code and a concise README for redeployment My background in Informatics and system optimization helps me design responsive interfaces and robust backend API logic, even for simple tools like this. I also work comfortably with structured and unstructured data across SQL (T-SQL), MongoDB, and Redis, so I can keep the solution efficient and maintainable. If needed, I can also use Claude/ChatGPT-assisted validation logic to speed up delivery without sacrificing code quality. Do you prefer the form to be hosted entirely on Google Apps Script, or would you like a Firebase-hosted frontend with Apps Script handling the Google Sheets write/duplicate-check logic? Best regards,
