The 1.1 update to Export It is a big leap forward in terms of ease of use for the Control Panel export as well as some updates to make the REST API way more useful for your ExpressionEngine site.

Control Panel Export

To start, the Control Panel export has been reworked to add in visual filtering. Now, you can see what you're about to export before getting the file so you'll know what you're getting.

You can search for items by keyword, date range and, depending on what you're trying to export, user group, channel, and status. See the Control Panel export docs for details on all the filtering options available but suffice it to say that you can export, for example, only the entries from channel 6 with ExpressionEngine in them between Jun 6th and August 3rd of last year.

Another addition, and probably the most requested, is that both Channel Entries and Comments can now be exported in Excel format. Most custom Fieldtypes, like Matrix and Channel Images, are taken into account and no data is lost in translation. Take a look at the docs for a complete list of supported custom Fieldtypes. 

REST API Server

In terms of the REST API every method got an update in terms of parameters they accept. Every request can now be have a limit and allows for pagination, searching, date ranges and status filtering. The docs have also been updated to reflect all these changes and to help out with any questions.

Speaking of the docs, along with the updates to highlight the current features, the docs have been updated to show how easy it is to create custom API methods to extend the REST server. There's even an example extension to help get you started.

You can buy or download the update from both Devot:ee and CartThrob.com.
