How to export from various Google products in one click ?

So you have a Google account (who in this world doesn't ?); have used quite a few of their products like Picasa web albums, +1s, Google Buzz (which is going away soon), Google Voice, Contacts, etc. and want to export everything easily in one click ???
Google Takeout is the answer !!! This web application allows you to take all your Google data out in a portable manner. The exports are easy to open in tools which are found in almost all PCs. For example contacts are exported in .vcf files which can then be imported in other address books. But something like an export of all Buzz updates proved to be quite useless. Not sure what people would do exporting all that junk :)

Looks like there is some kind of a war going on between Facebook and Google to prove who is better is providing 'data portability' to all their users.

Export Google Calendar to Excel

If you are someone who uses Google Calendar excessively and always thought about exporting it to a Microsoft Excel file so that you can analyze your hours in the tasks that you have spent, you can use many applications that are available on the net. One such popular site is http://www.gcal2excel.com/. Give it a try and see if you like it.
You would definitely have to be a Google Calendar user though to use this feature. If you haven't used it at all and grant access to this site to export your Calendar, it will throw up an error.
