I have a large source data file that I need to incorporate into my Excel
worksheet. If I record a macro while opening the file, I get the following; each field has an indicator that makes it text, date, or whatever format I selected. However, this opens the file as a new Excel sheet, whereas I need to just load it directly into memory. Sub OpenCOLAStxtFile() Workbooks.OpenText FileName:= _ \\SharedNetworkDrive\Folder\Subfolder\Filename.txt ", Origin:=437, _ StartRow:=1, DataType:=xlFixedWidth, FieldInfo:=Array(Array(0, 1), Array(40 _ , 1), Array(51, 1), Array(73, 1), Array(94, 1), Array(135, 2), Array(176, 1), Array(217, 2), _ Array(238, 1), Array(249, 1), Array(259, 1), Array(270, 1), Array(292, 1), Array(313, 1), _ Array(354, 1), Array(394, 1), Array(436, 2), Array(477, 2), Array(498, 2), Array(539, 3), _ Array(550, 1), Array(562, 3), Array(574, 3), Array(586, 3), Array(598, 1), Array(600, 1), _ Array(602, 1), Array(604, 1), Array(625, 1), Array(637, 1), Array(648, 1), Array(689, 1), _ Array(730, 1), Array(737, 1)), TrailingMinusNumbers:=True Range("A2").Select End Sub The second macro (below) is what I use to open text files and parse out the contents into memory (or dump to a sheet). Is there an optional parameter on the commands that read the text file that would make it easier to force some of the columns formats away from what occurs with general formatting? Heck, is there a better way altogether to pull in the contents of a fixed-width delimited text file? This seems clunky to me; I'd rather just read a line at a time and split it, if that makes more sense. Thanks!
