Import e-mail "from" aadresses from Outlook inbox to Excel

[maku220]

Hi, first of all I'm new to this forum so if this topic is in the wrong subforum then please forgive me.
Also sorry for my bad english.

My problem at hand right now is that I need to get a list of all the e-mail senders (e-mail addresses who are they all from) from Outlook inbox , I used all my current Excel knowledge + Google info but the result turned out quite a mess and it didn't serve the full purpose. I exported a .CSV file from Outlook inbox and imported it to Excel and filtered all the cells that contained the word "from:" but since the imported data from Outlook was a chaos on itīs own then the end result was too. (it didnīt contain all the addresses)

Does anyone have an idea how to achieve this with 100% accuracy?
I would be very much thankful.

If I couldnīt send a clear message through my faulty english then please say so, I will then try to explain it better.

Okay I think I got it now, I had to export .CSV and not all the contents but to filter only "From: (addresses)". Didn't know there was this function until now. But still I'm paranoid if this list now contains all the info I need or not.
Is it just me or if given an important task regarding data handling and there's no way of checking if it's all correct even if it should logically then this paranoid feeling doesn't go away, or is it a common problem?
