Finding and removing hidden characters in your data using dynamic T-SQL

Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to float.
However, my data was numeric I checked it many times… or was it really 100% numeric?

Power Pivot and Power View now available in Excel 2013.
In Excel 2013, much of that functionality, including the infrastructure that supports it, is built directly into the Data Model in Excel.

You have to do some menu/dialog box acrobatics to turn them on, but it’s a one-time set-and-forget requirement.
If you’d like to try it yourself, click through File|Options|Add-Ins|Manage COM Add-Ins|Go… and then enable the add-ins by checking them off and clicking OK.
