Excel Tip: How to Easily Remember the Index-Match Formula

0 comments
Lots of experts tout Index-Match as a better look up formula than venerable Vlookup.  However, it's a little hard to remember its formula (which is a mash up of the Index and Match formulas).

Here's how I do it:

=INDEX(Range with values I don't have, (MATCH(Look-up value, Range with values I do have, “0″))

Everything I have goes in MATCH; what I don't have goes in INDEX.  For example:
  • Range with values I don't have = Range of product IDs
  • Look-up value = Product Name
  • Range with values I do have = Range of product names
The 0 at the end of the formula means you're looking for an exact match.  Check out the Index-Match article linked above for a fuller explanation.

Ever want to bold a cell in Excel based on the contents of another cell?  Here's how...

Say you need cells in column P to be bolded if column A contains the word "total."  To do this you'd:
  1. First, select the cells that you want to which you want to apply conditional formatting.
  2. Then click Conditional Formatting from the top ribbon.
  3. Next select New Rule.
  4. Then click "Use a formula to determine which cells to format."
  5. Enter this formula in "Format values where this formula is true": =ISNUMBER(SEARCH("total",A1))=TRUE 
  6. Select your format; in this example, you'd use bold.
After this all the cells that have the word "total" in them cells against them will be bolded.

Excel Tip: Abbreviate Large Chart Axis Numbers

0 comments
Charts are important way of summarizing data in Excel.  For them to work best, they need to be uncluttered.  One way to clean up a chart is to replace large numbers with an abbreviated version.  For example, you could replace 1,600,000 with 1.6M.

To do that, right-click on the chart's axis and select Format Axis.  Then click on Number in the dialog's left column and add this code in the Format Axis's Custom section:

[>=1000000]0.0,,"M";[>=1000]0,"K";0

Excel Tip: How to Not Show Zero Values in Percentages

Often not showing zero values in Excel makes data easier to read.  Percentages by default display zeroes; if you want to replace that with a dash, blank, etc. use the following formula in the Custom Format section:

0.00%;-0.00%;"-"  (you can replace the "-" with blanks (" ") or anything else)

The easiest way to bring up the dialog is by hitting CTRL+1, which will get you what you see here:
