    Something that can be very handy when youíre building a dashboard is to return a certain picture depending on a condition. We can use VLOOKUP to look up data in a table and return the corresponding value from a different column, but unfortunately we canít do that with pictures... or can we?

    This example shows how to accomplish the equivlanet of a picture VLOOKUP, and is based on looking up a picture to display the appropriate icon for a weather forecast; something we use on our dashboards from our golf course. We update the weather data daily via a weather feed, and really donít want to have to manually update ...

    Conditional formatting in Excel is a powerful tool that allows you to dynamically format cells depending on the values of that or other cellsí data. In Excel 2007 the conditional formatting engine was re-written, opening things up to allow more than 3 conditional formats on any cell, as well as conditional formats that could overlap ranges. All in all, these were fantastic improvements that can lead to some very versatile and useful worksheets.

    Unfortunately, the user interface to control conditional formatting is not the most intuitive. The purpose of this article is to help you understand the way Excel applies rule precedence so that you can build powerful formatting rules of your own, without getting frustrated along the way.

    One of the things that always struck me as odd about using subtotals is that only the words in the subtotals turn bold, and not the actual subtotals themselves. With a long list of data this can make it hard to see which numbers are the subtotals amongst the data. Fortunately this is very easy to fix using conditional formatting.

    The purpose of the VLOOKUP function is simple: it looks up data in tables and returns results from a different column. So if you have a table of products, for example, you could ask VLOOKUP to return the price for an item given the ID of the product.

    But VLOOKUP is more than just that; it is the gateway to real Excel knowledge. The VLOOKUP function contains everything that a function can throw at you: multiple required parameters, optional parameters with defaults, and needs both ranges and numeric data in its input strings. If you can master this function, you can master ANY other function in Excel.

    Introduction
    How many times have you built a table of data, and put totals on it. You ship it out the door, and another user comes along and inserts a new row right before the totals row? If you have seen this in play, you'll know that the new row is actually inserted between the end of the data range and the totals row, meaning that your sum formula no longer picks up the entire range of data!

    Fortunately, the issue with missing rows in totals can easily be fixed so that a user can insert a row immediately above your totals without missing the last line(s). ...

    What are dates?
    This may seem like a strange thing to ask but, as far as Excel is concerned, dates are numbers. By storing them as such, it gives us the ability to add or subtract days to/from a date, as well as get the difference between two dates. If dates were stored as text, this would not be possible. Storing dates as numbers also allows us to construct far more complicated formulas, based on results that we may want to know.

    This page is dedicated to explaining how to use what I believe are the five most valuable formulas for working with text in Excel. They are useful on their own many times, but can become immensely powerful when nested (combined) with other formulas later as well. Mastering these five formulas will open up the door to many things that you may have never thought possible. All of these formulas can be used by putting actual text in the "text" area, but their true power is unlocked when using them on cell references as the data can then be dynamic.
