Hi,
I've googled and moodled for a while in search of a simple spreadsheet (without macros and other complicated and version specific stuffs) for writing questions that can be imported in Moodle 2.x/3.x in the GIFT format.
At last I've done this simple spreadsheet with two sheet:
- ODS where you can write your question and answers
(remember to exclude some characters, to check the question type and to assign grades) - GIFT from which you only need to copy the code.
Tell me if you find bugs or if you find it useful, thanks!
