Which of the No Code products should I start with?

I want to create the following application and I need someone who can recommend me which NoCode application will work.

I would like to add an additional application to my website

- The user should have the possibility to search for a file. e.g.: 123.exe

- The application searches in my database (excel) for the name

- if there is a hit, the information I have created for this file will be displayed.

- if there is no hit another Text should be shown as default

The application should be created once without having to pay monthly fees.

Are there any pre-built templates? Since this was a simple application it should be easy to find this?

Thanks for your help
