There're some options:1. In Excel, select desired cells range and give it a unique name (you can specify range name in area left to functions button).Then in ArcGIS you would have this name displayed without $.2. In Calculate Value model-only tool try this:Expression:removeChar("%Value%")Code Block:def removeChar(val): if val.endswith("$"): return val[:-1]
ordef removeChar(val): return val.split("$")[0]
and use output inline variable from this tool to name resulting feature classes.
