We want to export more than 50 columns but "Export Data Store Entity to Excel" supports only maximum of 50 columns,
And also exceltool plugin has "[Deprecated] Export CDT To Excel" so its not a solution. And based on the below reference its not possible to append extra column for the same set of data.

Is there any other smart service or solution that we can apply here to export more than 50 columns?

If it helps at all (at least as a temporary workaround), the current version of Excel Tools on current Appian installs, still allows you to use the deprecated Export CDT to Excel node - it works fine (last I checked) despite being labelled "deprecated". Despite its deprecation, there's never really been any sufficient replacement provided, so I still use it with no guilty feelings when it's necessary for my requirements.
