Please tell me: What cosmetic adaptations do you want to make?
The formula for all entries in my table is the same but it assumes certain relative
positions between the deg columns, the arc min rows and the specific entry cell.
So, when you reformat that table, these references might get disturbed and
the entire table becomes garbled.
Accordingly, there might be no such thing as reformatting without reprogramming.
If you'd like to do it by yourself: The formula I used is:
hav(x) = [ sin( x/2 ) ]^2
where angle x is : # degrees + #arcmin/60 and expressed in radiants.
The get angle x in radiants, you take angle x as measured in degrees,
divide that number by 180 and multiply the result with pi.
Strangely, in excel pi is expressed as PI().

Herman,
come to think of it: Please tell me: What cosmetic adaptations do you want to make?
If the changes are not too complicated I am happy to do this for you.
Therefore starting from scratch might turn out much simpler over all.

hav(x) = [ sin( x/2 ) ]^2
where angle x is : # degrees + #arcmin/60 and expressed in radiants.
The #degrees and #arc min are located in the top rows and the marginal
columns, respectively
columns, respectively

Hello Hanno,
If I have understand it correct, you have produced the 2 pages 4 digit haversine table.
Can you supply me (or us = navlist community) with the xls file?
I want to make one cosmetic adapth so it fits more for me.
regards
