So far I know…and I don’t know so much, Excel Online runs on limited features.
Nor, as far as I can understand, is there an acceptable substitute for a beginner or for creating a simple diagram.
Adding a trend line is a basic requirement for excel (in my opinion, it doesn't have to be the right one for everyone), Online version does not have this function.
As an example... The point of making a chart (standard curve) is so you can calculate an unknown value using the equation of a line. For this, you need a trend line.
It should also not be forgotten that not all students have the option to buy Office 365, many use the online version.
In my opinion, Excel (and the whole Office) has conquered the users not because there is a gigantic company behind it, but because it is very easy to use for every beginner and at the same time offers a lot of possibilities for different applications for professionals. It unites the amateur with the professional, it unites the future users with the long-term users, and it brings together ideas that can be shared and developed, from beginners to professionals.
That is why it is always good to think in advance whether a function is to be incorporated into further development or not.
I am also sure that there can be valid reasons than just these that I have listed, but the professionals can list them here.
Thank you for taking the time to read my opinion.
…and please don't forget, it's only my humble opinion ... because I know that I don't know anything (Socrates).
