Google announced on the Google Webmaster Central blog that you can now download many of the “heavy” data directly into a Google Spreadsheet format.
The new download options are available in the Crawl errors, Search queries, Links to your site and some other areas. You can click on the download button in those reports and then “Select Download Format” as “CSV” or “Google Docs.”
Choosing “CSV” initiates a download of the data in CSV format which has long been available in Webmaster Tools and can be imported into other spreadsheet tools like Excel. If you select the new “Google Docs” option then your data will be saved into a Google Spreadsheet and the newly created spreadsheet will be opened in a new browser tab.
