Sort left to right

This macro will sort (A to Z, case insensitive) by row level at the current cursor (or selected cell) line. You can use this macro to develop further for different sort criteria.

function SortOneColumn( yLine )
{
    count = document.GetColumns();
    arr = new Array(count);
    for( i = 0; i < count; ++i ) {
        s = document.GetCell( yLine, i + 1, eeCellIncludeNone );
        arr[i] = { name: s, col: i };
    }
    arr.sort( function( a, b ) {
      var nameA = a.name.toLowerCase();
      var nameB = b.name.toLowerCase();
      if( nameA < nameB ) {
        return -1;
      }
      if( nameA > nameB ) {
        return 1;
      }
      return 0;
    });

    bSorted = false;
    for( i = 0; i < count; ++i ) {
        if( arr[i].col != i ) {
            document.MoveColumn( arr[i].col + 1, arr[i].col + 1, i + 1 );
            bSorted = true;
            break;
        }
    }
    return bSorted;
}

yLine = document.selection.GetActivePointY( eePosLogical );
while( SortOneColumn( yLine ) );

I am not sure what you mean by 1. On delimiter level.

I am still not sure if I understand your question, but if you are talking about a nested CSV like this page:
https://www.emeditor.com/text-editor-features/more-features/nested-csv/

and if you would like to sort, for instance, “apple;banana;cherry“, you can select “Split Columns” while selecting the second column, select (None), enter the separator (a semicolon in this case), set the Sort split strings option, and select a desired sort criterion.

OK. I now understand your question.

Currently, you can select a CSV mode (for instance Tab-separated, NOT Comma-separated) so that only one column should exist. Select the only one column, select the Split Columns command, then select (None), enter the Separator (Comma + Space in this case), set the Sort split strings option, and select a desired sort criterion.

Alternatively, you can split to multiple lines by replacing Comma + Space with a newline, sort, and then replace a newline with Comma + Space to restore newlines.

I will think about a new command in the future.

We’ve just released v22.0.901.

– Added the Sort/Remove Duplicate split strings in Selection, Sort Columns, and Manage Columns command.
