saywell Posted May 24, 2012 Posted May 24, 2012 I'm a very basic excel user, and have never before needed to use the Excel UDF. I have now been asked to write a script that will process a very large csv file, which will mean working through each cell column by column, altering its content according to set rules. This looks quite easy using _ExcelReadArray and its write equivalent, then looping through it doing what's necessary. However, the files are huge - the first is over 12,000 rows and will get bigger each quarter through the year. My question is; how do I get the number of rows? _ExcelReadSheetToArray gives the number of rows in [0][0] but it takes ages to read in [hence my doing it one column at a time]. the ReadArray function requires the number of rows to be provided. Is there a more elegant way of getting this value? Regards, William
water Posted May 24, 2012 Posted May 24, 2012 You could use _ExcelBookOpen and specify the CSV file to open. $oExcel.ActiveSheet.UsedRange.Rows.Count should tell you how many rows to process.
