I have been utilizing your resources for 5+ years. I'm a stress engineer, so sifting through tons of raw data and outputting something useful with little individual input is the name of the game. Your stuff has been without question my favorite resource. Clear. Concise. Exactly what is needed.

Excellent, as always! Best cristal clear VBA tutorials ever! I've learned a lot form you! Thank you for that! Please, share us more of your knowledge! AI can automate tasks, but human makes them personalized. So, for Excel dependent jobs, VBA can help a lot if deeply understood and learned.

[@alexandrumarcel3696]

one issue I was facing when working with copying arrays is that if you have a column (or more) that is containing string values that starts with "0", the destination range needs to be formatted as text (.numberformat = "@"), otherwise the leading 0s will be truncated.

[@johnbutler2750]

If your numbers are of fixed length you can always just add zeros to the front and take the right of the required length, then number value of that Always a pain on bank details and phone numbers Tho it’s more annoying working with sort codes as some of the time it converts 6 digits separated by hyphens to dates

[@alexandrumarcel3696]

@@johnbutler2750 your solution for a simple copy paste will add a lot of extra effort to implement, especially if you have more columns that are not always being pasted into the same cells

[@johnbutler2750]

@@alexandrumarcel3696 meant it as a more general solution, either use a custom function to apply it when called in a larger macro, or as a nested formula to apply to an entire column then copy-paste as values (depending on how often it’s used)

Hi Paul, you are amazing, i also download your ClsArray2D class module, and take so much benefits, thank you, now am also able to make my own function for arrays current region, or clear existing data,,. I also download this one , thank you so much for your free help😊

[@СергейШлизенбарт]

Hi, Paul. Great tutorial as always. However i ve encountered with difficulties when sorting an array at the very last step. I fail to sort it with one line worksheetfunction approach (No method is found).Other youtube tutorials also provide some longer solution on array sorting. Is there any trick that i ve missed?

[@daveyks1]

Love this video! Do you program in Access VBA? Please would you do one for Access if you do? Thanks!

[@Excelmacromastery]

Glad you like it. I haven't used Access in a long time .

[@Art8157]

Paul, thanks for nice and detail comments. I have one question, why when I use "marks = shMarks.range("A1").Value" I receive error 424 (Object required). And it works when I write "marks = Sheets("shMarks").range("A1").Value".

[@Excelmacromastery]

shMarks should be the code name of the worksheet

Hi Paul, Realy enjoyed the webinar, Thanks. I did run in a problem with the code, trying to filter I get the eror " unable to get the sort property of the worksheetfunction class" on line "outputArray = WorksheetFunction.Sort(outputArray, 4, -1)" . any ideas?

[@Excelmacromastery]

You need Excel 2019 or later to use the sort function.

[@daneasch9703]

@@Excelmacromastery Thanks Paul, that explains it. Nice webinar, again. Like the lenght.

[@Dexter101x]

I don't mind the longer format, but would like shorter ones as well Is there something wrong with using xlDown as oppose to xlUp?

[@Excelmacromastery]

It will stop at a blank row if searching from the top.

[@stevetatterton]

I would suggest the GetCurrentRegion function should call another function to remove heading lines but setting the current region property outside of calling that function. Then the inner function can be used to remove headings from any region even if current region isn't to be applied.

[@dheerajjain5754]

Can we use arrays to copy all file names from a folder and paste it in an excel range? I am currently using "Copy Path" menu item to copy all file names which are there in a folder and pasting them in excel because it is simpler and time saving than running a macro which reads each file one by one and copies its name.

[@Zboob999]

Nice. What about Typescript for Excel ?

[@Excelmacromastery]

I have some videos on Office Scripts which using the TypeScript language for Excel.

[@trevormckerrow1460]

As always your tutorial was very informative. One issue; I get a runtime error when calling the worksheet sort function. This function seems to be unavailable in my workbook. Do you know why?

[@YvesMédardNGWAT]

Hi Mr KELLY. Hope you're fine. I guess you've heard about Office script. My concern is to know if VBA is will still be used in the 5 or 10 next years?!!! Is Office Script is replacement!! I've got those worries since I read somewhere that Microsoft will definetively discard VBScript from Windows 11. Do you have clear and trustfull informations about that topic?

[@Excelmacromastery]

Office scripts is not a replacement for VBA. The VBScript update, as it stands now, will only affect regular expressions in VBA.

[@JAY_DJ]

Thanks for sharing valuable information. I am already using array but it is still taking time to process big datasets. I have checked the number of iterations is more than 30+ million. Please can you tell me is there any way through which I can use GPU or multi-thread? I have done a lot of research regarding this and someone told me to use opencl but unable to find the library. I have tried to find some third-party tools also for parallel processing but I haven't found any tool yet. Please can you help me that would be great.

[@suvadipkundu152]

Hi, would you like to elaborate on the problem statement a bit.. for example, would 30 million iterations mean that you are accessing data from multiple spreadsheets? What type of validations/logic are you processing? Can you employ 'divide and conquer' approach? Finally, have you looked at using Excel's ETL backbone, power query as a solution? I do not know the performance criteria you have so if you can throw some more light on the same that will help .. Cheers, Suvadip

[@johnbutler2750]

I don’t think vba is the best tool for massive datasets. From my experience once you’ve done the usual disabling calculations, events and screen updating and are doing most of the work in arrays thats about as fast as you’ll get (advanced filter can be faster for large filtering operations). I believe vba is single threaded (worksheet formulas can use more) this can make large parallel operations slow I also doubt it takes advantage of the gpu much if at all. I think python may the better tool to use for large data analysis

[@haidereasa]

[@peterwooldridge7285]

[@omaraissa318]

i didn't watch the video but i have a trick about array i don't know if you are aware of. its how to redim preserve an array's first dimension, we know that we can only redim the second dimenssion , so the trick is to fill your Array in reverse order what in first dimension go into the second and what in the second go into first dimension, so then you redim preserve the second dimension after that you transpost the array into a variant using worksheetfunction.transpose to get your initial copied range.

[@Excelmacromastery]

The problem is that Transpose has a limit of 64000 rows for arrays.
