Free Online Result Portal with CAPTCHA – Google Apps Script

A public result portal for a whole school, built to be handed out as a single link. A student types their roll number, clears a CAPTCHA, and their result card appears — pulled live from the Google Sheet the school already maintains.

Multi-class in one portal

Most result scripts handle one class and fall over when the school needs the rest. This one supports multiple classes in the same portal, so one deployment and one link covers the institution instead of a separate build per class.

Why the CAPTCHA is there

A public lookup with no gate can be scripted — someone enumerating roll numbers to harvest every result in the sheet. The CAPTCHA layer makes that impractical while staying invisible as a nuisance to the one parent checking one child's marks. It is a small thing that separates a portal you can publish from one you cannot.

The result card

Each lookup returns a professional result card with subject-wise marks and a pass or fail status per subject. Data reads live from the sheet on every search, so a correction made by a teacher appears immediately with nothing to republish.

Who it suits

Schools and colleges publishing termly results, coaching centres and academies sharing test scores, and anyone who currently emails result PDFs one student at a time.

Setup

Copy the sheet, enter your marks, deploy the script as a public web app and share the URL. No server, no backend coding and no database. The video covers the full build, and support is free if you get stuck.
