Hi
You posted to the Office Insider forum, which is for Beta Channel users. The version you have is not the current Beta Channel build.
To get the Beta Channel Build use the Help menu in Excel. Choose Check for Updates, which launches AutoUpdate app.
In AutoUpdate, click the Advanced button, then switch Update Channel to Beta Channel. Once you have installed the Beta Channel update, you should find PowerQuery on the Data tab of the Ribbon.
