Google allows third party 'add-ons' on Google Drive

Google has reportedly revealed that they are rolling out an online marketplace for third-party apps on Google Drive.

The web giant has tagged these apps as 'add-ons', which are now available to Google Drive users in Docs and Sheets, the free online word-processing and spreadsheet services.

According to Mashable, the add-ons, which are created by third-part developers, allow users to do things like sign documents, create customized email templates or make name tags from within documents and spreadsheets.

In order to use this new feature, users need to select the new 'Add-ons' tab from within a document or spreadsheet, then hit 'get add-ons' and from there, users may use from the few dozen apps currently available in both app store and once an add-on is installed, it can be used from within any document in Google Drive, the report added.

However, these 'Add-ons' are only available within the latest version of Sheets, which Google launched last year and they need to be upgraded before using.

Once the preview phase is over, any developer will be able to publish an app to the add-on stores for Docs and Spreadsheets.
