Not updating would cut yourself off from future updates of both the script and sheet which is likely not what you want. The script has lost no functionality. If you've acquired data from somewhere then just acquire it again. You'll only need to update your format if you've created custom data. If that's the case here are some samples that are available in the SRD data included with the script: {
