New Google spreadsheet Concatenate limit 50000 characters

Question

Migrating to new Google spreadsheets. I have a custom formula that combines a few arrays into one array

=TRANSPOSE(SPLIT(ARRAYFORMULA(CONCATENATE(\'Monthly lin

Answer 1

My answer is related to another similar Q, marked as duplicete:

Text result of JOIN is longer than the limit of 50000 characters

My solution is to use the formula:

=query(joinSplit(A2:A, ";"), "select Col1, count(Col1) group by Col1", 0)

where joinSplit(A2:A, ";") is a custom formula.

The code to paste into script editor is:

function joinSplit(column, delim)
{
  var result = [];
  var row = [];
  for (var i = 0, l = column.length; i < l; i++)
  {
    row = column[i].join(delim).split(delim);
    row.forEach( function(elt) { result.push([elt]); } ); 
  }  
  return result;
}

It will return the column of unique items.

If data is:

A;B;C;D
D;D
E;F;A;A
G;A;B;C

The result is column:

A
B
C
D
D
D
E
F
A
A
G
A
B
C
