Hello, I found a nice formula to manage arrays, but I do not have idea why this do not work with 0D arrays (unique cell) and 1D arrays (rows or columns), but this work correctly with 2D arrays.

for example, when I use this =JTM2dSplit(IFERROR(FILTER(M53:N60;L53:L60=1);"");";";";"), this return #value, but when use =JTM2dSplit(M56:N56;";";";") , this work correctly. I found that any formula like filter that return 0D or 1D array, the result is #value, but if I use another cell like support, then this work correctly.

the values used are: L53="2" M53="220" N53="220" L54="2" M54="220" N54="220" L55="2" M55="220" N55="220" L56="1" M56="220" N56="220" L57="2" M57="0" N57="0" L58="2" M58="0" N58="0" L59="2" M59="0" N59="0" L60="2" M60="0" N60="0"

Can someone help me to fix this code VBA excel?


here the code:

Hi,

I'm not sure I fully understand what you are attempting to do, but it seems like you are trying to split a cell value with a delimiter at some point. If that is the case, try the formula =textsplit() already built into Excel.

>the formula =textsplit() already built into Excel.

the formula =textsplit() already built into Excel 365.
 
=textsplit does not appear in my MS Office 2021 version. What should I do?
 
If cellValues is passed as range, after cellValues = cellValues.Value2, cellValues is either 2D array or single value, and it seems that it is processed properly.

For me the issue is in IFERROR function. =IFERROR(FILTER(M53:N60;L53:L60=1);"") returns first argument if it is an array formula, otherwise the second one. So the question may be how properly pass range/array to your UDF. As a first test I would remove IFERROR function in argument. I have no FILTER function in my Excel to test, if it returns Range, it should be enough.

BTW, for me the functions Handle1DColumnArrayInput and Handle1DRowArrayInput do nothing, as the value from single row/column is a 2D array too.

Thanks for the help, until I understand, this VBA script only manages 2D arrays, but contain code to manage 0D and 1D arrays management...

... Then the solution is change "cellValues As Variant" to anything that accept 0D, 1D, 2D arrays, how do this change?
 
I understand 1D and 2D arrays (well, even 3D arrays, like a Rubik's Cube), but what is a 0D array?

Just curious... [ponder]

So, '0D array' is a 1D array with just one element.

When you pick data from excel range you get either single value (from single cell) or 2D array. It would most straightforward to count the input cells, if 1 then assign the value to 1 x 1 2D array.

If 2D array is not the only output option, 4D array can be alternative, with the last two dimensions for splitted values.

Have you solved your initial problem with UDF #value return?

I am not too good with VBA, I did not found any error in the vba, should work, but I still have same error when I use 0D and 1D arrays.
