    Lightbulb .csv Import. Resize table to match data set

    I have written a macro module to aid users import .csv files into some empty tables ready for further analysis. These .csv files always contain three columns of data, but the amount of rows varies greatly and can be in the thousands. Previously we used to copy and paste values, but this is notoriously slow. Instead we have switched to using ''Range.Value ='' (shown in green below).

    This has sped things up massively, but I am struggling to size the receiving table to match the amount of rows from the incoming data set. As a work around I have just manually set, using a resize function, to a value that I know to be larger than the amount of rows in the data set (shown in blue below and set in this example to 100 rows). This will then just show any empty rows as #N/A. Not pretty!

    I could write some code to remove the #N/A rows, but I am sure there must be a neater way to do this from the off. Can anyone let me know how to code this so each table will match the size of their imported data set? I have attached a striped down version of the macro file along with a test .csv file to allow you to try this out. Thanks in advance for any help.

    Re: .csv Import. Resize table to match data set

    This works perfectly, thank you ikboy! Its always a thing of beauty to see my janky coding simplified to something so elegant.

    For the purposes of bettering my knowledge would you mind just putting some wording to the logic of the below highlighted sections. I follow everything else but this bit is new to me. In the future I may need to change the columns being imported (for example columns D & H, or maybe even import a third column) so would be good to know how to modify this correctly to suit.

    Thatís perfect thank you. Figured out how to chop and change columns and bring across additional ones too

    Only thing I canít figure out is how you would modify to ignore the first row of the .csv data set. Sometimes this contains heading to the columns of data so I would need a way to only look from cell A2 onwards. Is this possible? Suspect I am missing something easy!

    Re: .csv Import. Resize table to match data set

    I thought it may be a case of changing the below line from (1,1) to (2,1) but when I run the macro it always imports the first row as well.

    I see now that the 'CurrentRegion' function will grab values from all cells that aren't blank, so this is why it always include the first row even when stating (2,1), as in my case they will include titles for the columns. So I guess what is needed is another line of code with an 'Offset' function perhaps. Or maybe it could be integrated into this same line somehow? I have googled around an cant find the right method...

    Think I may have got something that works to ignore the header row. But if possible to do more simply please let me know! Thanks
