How do I 'unhide' something in Excel?

[BecauseImWoeufIt]

I have a spreadsheet that has been sent to me, and I'm trying to work out how a particular calculation has been made, but 6 columns are hidden. I'm assuming that the calculations/formulae are in these columns.

How do I unhide these, please?

Or, if I'm not the creator of the spreadsheet will this be possiblE?

Thanks!

Highlight the column heads, the 2 either side of the missing columns, then right click, unhide.

You should be able to do it easily - in the 'Windows' option on the toolbar - there is an unhide option.

Or if they have just made the columns very thin - highlight the columns either side and then make them all wider.

Depends whether or not they have protected them
Try highlighting the columns then click 'format' at the top, then 'columns', then 'unhide'

Brilliant - thanks!
