How do I embed a single entry to a web page?

This can be solved by simply embedding the "printer friendly version" of the form. In the spreadsheet form, go to an entry, and choose Printer Friendly under Tools. This will take you to a page with a printable version of this entry. You can use an iframe to embed this page to show the detail of one page.

This can also be resolved with our HTTP API, which will give you a JSON format of the data, you can just replace www.ragic.com with api.ragic.com to get this URL for pages that do not require authentication.
