What do you wrote first ?

General
1

In File In / File Out as in Conversion (html, JSON, XML, whatever), format A to Format Bor Format B to Format A, what do you write first:

a. “Read” Method ?

b. “Save” Method ?

c. “How do I deal with Read / Write“ ?
And explicit your choices in the document.

PS: I wrote Read / Write because everyone I know say that in that order, just like in File In / Out. This is not a clue for an answer.

Always the read.

That way I can use the debugger to watch each part being processed.
