I am trying to import/attach excel data (MaxTemp, MinTemp, precipitation) to a multi-point shapefile. Is there a faster way of doing it other than editing each point shapefile attribute table?
I take it you have a common item between the two tables right?
My personal approach would be to create a database table from the excel data. And, assuming that when you say shapefile you really mean point feature class, you should probably put the the excel data into the same database as your points. Then use a relate to see what data go with what points, via the common item.
