How to Merge rows in Google Sheets

Question

I tried digging this stuff and have no solution so I'm hoping someone can assist. I have a sheet with the following:

Data

123|456|789        
111|222|333        

etc...

Result Needed

|123 456 789|        
|111 222 333|        

etc...

I'm trying to avoid formulas ( =Concat ) and ( =A2&" "&B2&" "&C2 ) etc...

I tried sheet.getRange(2,1,1,2).mergeAcross() ; and it merged the cells and kept he left-most value. Google searches point to the formula solution.

Answer 1

You can try Array.join() for each row:

Snippet:

var jointRowsArray = sheet
  .getRange(2, 1, 2, 3) //A2:C4
  .getValues()
  .map(function(row) { 
    return [row.join(' ')];//join Each row
  });
sheet.getRange(2, 4, jointRowsArray.length, 1).setValues(jointRowsArray);

Answer 2

var range  = sheet.getRange(2,1,1,2)  
var values = range.getValues()

range.clearContent()

sheet.getRange(2,1).setValue(values.join(' '));

You can pull the values into JS and then join and insert them into a single cell. You can also place this inside an iterator and do something akin to getRange(i,1,1,2) . This can be triggered manually or by an edit hook.

However, this seems like the perfect fit for a single formula.

=TRANSPOSE(QUERY(TRANSPOSE(A:C),,COLUMNS(A:C)))

The formula would go on the first row in perhaps column D. JOIN functions cannot usually be arrayed in google sheets, and you would normally have to put a formula in for every row. However, here we are tricking the sheet into thinking our data is the header and displaying it accordingly.
