Thank you so much for posting your process BDMcGrew - this was the additional information I needed when my "gear" disappeared in Internet Explorer so I could not get to the export data option.  I also could not get my client list to appear when I logged into QBO on Internet Explorer.  I ended up clicking on the Work tab on the LH side to get to that specific client.

I substituted https://c70.qbo.intuit.com/app/homepage with  https://c70.qbo.intuit.com/app/exportdata and all worked fine afterwards.

This was  super frustrating process as our IT people do not give us access to modify Internet Explorer options on the Security tab.  I had to do this all on my personal laptop, including installing my work version of QB Accountant to get it all to work.  It would not work with the trial version I downloaded.
