Is it possible to collect from data in excel or CSV file using HTML5 Local database only, without using Mysql?

It's a example:

I have a HTML form on a webpage

I want to collect all data of form ( Data, which user will submit) in Excel or CSV sheet.?

Is it possible with HTML 5 only? or will be required Mysql, php, apache etc?

Browser I will use is : Google Chrome , no other browser need to consider

Application will run on local PC. if it's not possible with HT开发者_StackOverflowML5 local database, I will install portable XAMPP.

Any demo , example would be appreciated?

LocalStorage is a key/value store, and there's not really any way to change the way Chrome decides to save that data in order to get it to write it to a CSV file instead.

Maybe try using an html5 web sql database rather than local storage, since you're dealing with tabular data.
