i wrote code , excel template has changed (the first column no longer in need), there way move entry code 1 column left instant of correcting step step? for example(this old code): .range("i1:j1") = array("check", "key") now need change to: .range("h1:i1") = array("check", "key") but it's long code , want know if there's way easier. thanks. i'd suggest using built in search & replace function ( ctrl + f ) . put like .range("i1:j1") into "find what" field and .range("h1:i1") into "replace with" field. if you're lazy hit replace button, can dangerous in possibly changing parts didn't want change. however, using replace button , going through entries can fast in longer code, , way can check each entry if it's correct change it.
