Understanding Society User Support

I am looking to download data in a format that I can ideally use in excel. If not, I am willing to download any software which will help me access the data. I am confused by the number of different data files available to download and am unsure which is best for me.

After downloading the British Household Panel Survey: Waves 1-18, 1991-2009 data file in tab format I have opened it in excel. However, it is in a format which seems impossible for me to understand.

I would be very grateful if you could provide exact instructions on what file I should download to access the variables I require as follows:

From at least 3 waves or more:

Household makeup / structure / type
Household income
Household wealth
Household financial assets
Household housing/property assets

Kind regards,

Chris
