I have data as follows in excel/google sheets. Numbers that have a length of 19 characters need to be manipulated in this way For all strings with a length of 19 last 6 digits need to be trimmed, ( i can easily do it ) and remove the leading prefix which is either 200 or 20000
for example 2005507187528000001 to 5507187528 | 2000017303364000001 to 17303364
Have no idea what to do to remove the prefix, I tried trimming the last 14 digits to get 20000 or 20055 and using this to determine if I need to take out the first 3 or first 6, but no success.
Please help !!!
thanks
