Hiding and Unhiding Columns

What is the downside of changing column width to 0.1 to hide it? Existence of hidden column by skip in the headings - e.g., AC when B is hidden.

Instead of using a macro to hide predefined columns for printing, why not set up custom views ? Doesn’t require VBA, file format stays xlsx and is easier to maintain (also more versatile as it also supports filtering and print area settings)

You might want to use my new FindAndUnhide macro in the M_Text module of My Excel Toolbox: https://sites.google.com/view/MyExcelToolbox/

@Andy
This might be a bit awkward, but after using Ctrl+F to find the hidden cell, press Esc to close the Find dialog then Ctrl+Shift+9 or Ctrl+( to unhide the row. To re-hide the row, press Ctrl+9. To find the next, press Ctrl+F+Enter.
To hide/unhide a column, use Ctrl+0/Ctrl+Shift+0.

I have a large worksheet and use the 'collapse row' function to make it look less busy. Problem is if someone searches for data that is contained within the collapsed rows, the normal Ctrl-F search will find it but just underlines the cell above which is not easy to see. Is there a way of a simple search opening the collpased rows to show the cell containing the searched date?

Why bother with the ribbon, except for unhiding columns?
Surely :
CTRL+9 hide selected row
CTRL+SHIFT+( unhide column in selection

CTRL+0 (zero) hide selected column

However, I have never gotten this to work. Is there a bug?
CTRL+SHIFT+) unhide column in selection

(I also use outlines on sheets I want to hide/unhide rows and columns frequently)

I like your hiding macro Graham; however; how hard would it be to have the trigger be a value rather than a comment? If the trigger is a value it can be dynamic. How would you change the code if it were say the value "True," in the first column, or even "Hide," if that's easier, rather than a cell comment.

Thank you Graham!

I find it easy to "GROUP" columns or rows (Data-ribbon, outline - Group) that I frequently should hide or unhide. You then get the + and -buttons on the side bar or top bar to expand or collapse grouped columns and rows. You also can "ungroup" rows and columns you do not want to keep into it. Adjoining columns and rows will be "grouped" together. If you want to collapse or expand them separately then it is best to insert a very narrow column or row in between.

Good luck.

If you regularly want to hide and unhide a pre-defined set of columns then the macro below could be used. For example I use this to hide some columns during printing.

All that you need to do is add a Comment in Row 1 for any column that you wish to hide. The comment should start with the characters HID, upper or lower case.

NOTE - When creating a new cell comment some versions of Excel start the comment with the user's name. This needs to be removed.

By use of the Static definition the macro toggles between hidden and unhidden.
