I need to interpolate data that I have in a excel file using data from an attribute table of a point feature. I want to create a new field on the attribute table with the result of that interpolation. The problem is that my data is on excel and I don't want to join the excel table with the attribute table. I just want to use the data from excel table to obtain a result for my attribute table.

Is there any way to do that?

Use map joins with field calculator. Map join won't add the fields physically to your table, rather, it is an in-memory join.

Right-click your layer in TOC > Click Joins and Relates> Join...

Then use Field Calculator to interpolate.

  • Ok, I'm seeing that the only way is actually to do a join
