Left click & hold on the top left cell you want formatted this way
While holding down the mouse button drag to the bottom left corner of the
cells you want to format and release the mouse button
All the cells to be formatted SHOULD now be boxed/highlighted, and the top
left cell should be within the box but not highlighted. I'll assume it is A2
Go to Format|Conditional formatting

In the left box choose "Cell Value is"
In the next box choose "greater than"
In the next box type (without the quotes) "=B2"
Click on the format button and choose a Red pattern & click on OK

Click on the Add button

In the left box choose "Cell Value is"
In the next box choose "less than or eqaul to"
In the next box type (without the quotes) "=B2"
Click on the format button and choose a Green pattern & click on OK

Click on OK

You should then have just what you wnt

This is what I want to do:

If value of cell A is greater than cell B then fill in red, if less fill in
green; if cell C is greater/less than cell D fill in red/green etc. etc.
Can I do this quickly without having to set the condition for each cell
separately. Also need to do this for several rows.

Sorry but definitely a novice when it comes to Excel

First select ALL the cells to which you want the formatting to apply
Then go to the Conditional Formatting dialog box and apply the formatting
conditions, making sure that the conditional formulas point to the cell
appropriate for the active cell in the selection. Also make sure you are
using relative cell references AND NOT absolute cell references

I have a table with several rows and columns from week 1 - week 52. I want
the formatting to be goverened by the preceeding cell values. I've formatted
week two (red if higher than week 1, green if same or lower) Is there are
quick way of copying this formula across the other cells and rows?
