Say you have a data set and want to make sure that each column contains what it is supposed to.
For example, say you have a column which contains Dates and you want to check that there are no cells which contain Text.
You can easily check this by highlighting that column and pressing CTRL+G to bring up the Go To dialogue box (or by choosing from the menu Home > Find & Select > Go To…)
Then you need to choose Special > Constants and select the constant that you want to find in your column.
In our example you will need to only select the Text box and de-select the other boxes and press OK. This will highlight the cells that contain text and you can begin to format these cells.
See how this is done by watching the gif tutorial below.
