If only thy were automated.
The first thing I did was to correct some cells, not because they were wrong, but because I use OpenOffice.
Second, pasting of level from hed editor to text editor, so I could make the lines the right length (number of characters) I have since found, but not tried hex editors that will allow you to control the length of the line.
Third, paste from text editor to spread sheet.
Fourth, run the function.
Fifth, copy from spreadsheet to text editor (to attach header DC expects for its levels).
Sixth, save as level.
