excel - Standard method for creating file read/write 'library'? -

-

i attempting create file read/write 'library' using excel vba old file format. info, format lis79, old oil industry format writing well-site data tape - largely streams of wellbore measurements density, resistance, temperature etc. full spec here (pdf doc) - it's pretty long , boring.

as i'm using excel vba guess it's not library, collection of subs , functions etc.

i have been tapping away month or , making progress, though it's becoming increasingly complicated - number of subs , functions need write keeps on growing.

i figure i'm not fist person try , write file read/write library it's specification. i've been searching stackexchange, searched using google , browsed programming books @ local university library, see if sort of standard process or method might exist make whole task bit simpler. alas haven't been able find anything, though have no formal programming background it's possible don't know precisely search for.

does know of standard method, procedure or guidelines creating file read/write libraries refer me to?

or matter of persevering - file read/write libraries can long , complicated things create?

many thanks.
