The Name Checker Utility, an Excel template (xlt), is a tool for assessing the compliance of a list of candidate data names in an Excel worksheet against the CMS Central Data Administration Standards. The tool is available for installation by clicking the Name Checker Utility download below and then selecting "Open". The necessary files will be saved on your computer automatically as part of the installation process.
If you have your Excel macro security set to Medium, then you only need to open the xlt file from this web site and it will ask you to Enable Macros and then will self-install. Otherwise, the User Guide contains more detailed information. The User Guide is recommended reading in any case and is available in the zipped Name Checker Utility download below.
