# Zip Code Radius Calculations with Microsoft Excel

"Custom functions of Microsoft Excel" can be used to perform a number of addresses and location-based information tasks, such as importing demographic data, checking the accuracy of the address, calculating driving time, and optimizing the route. Custom Functions, also called User Defined Functions (UDFs), perform complex calculations or tasks and are used in cell sets like standard Excel functions such as SUM or AVERAGE. In this article, we will discuss how individual functions can be used to identify postcodes within a specified distance or "radius".

Postcodes can be very useful for analyzing demographic data and can help you better target your customers and plan your marketing campaigns. For example, the identification of zippers in a specific radius of potential new store sites can help you choose the most appropriate location for your clientele. Instead of drawing circles on the map, a much easier approach is to use the custom function within Excel, which can do the job for you.

Suppose that we evaluate the possible storage location of zip 07470 and there is a need for a list of all zippers within a 10 mile radius. To use a function called RADIUS, simply type a formula in such a worksheet cell: "= RADIUS (ZipCode, RadiusDistance)". In this case, the formula "= RADIUS (" 07470 ", 10)" and the worksheet shows all results within 07470 miles.

The formula can be customized to display data as a text string. in a cell or in an array containing unique results in the spreadsheet. To return a formula in Excel, simply select the target range with the mouse, then hold down Ctrl and Shift, and then press Enter. The returned data may also include the calculated distance and may be arranged based on proximity to the target lock. You can add more options to return the distance in kilometers or miles.

The custom function automates the process of finding all zippers in a given radius by searching for a local database and calculating distance and latitude. All of these operations run in the background, so the user is fully working within Excel and sees only the list of zip codes that appear on the resulting worksheet – no new application to learn or import from a web address list.

The great advantage of custom functions is the ability to process large amounts of data in spreadsheet format. For example, to perform postcode calculations for a list of zip codes in column A, simply enter the appropriate custom function formula in cell B1, for example, "= RADIUS (A1, 10)", where "A1" is the location of the first zip code. Then copy and paste this formula in column B; this way, you can perform radiation calculations for thousands of zip codes without the time-consuming manual input required for other programs.

There are other useful Excel features that complement these radius calculations, such as calculating the distance between the two specific zip codes. In this case, the custom function formula would be: "= DISTANCE (ZipCode1, ZipCode2)". The calculated distance can be "a flies" or an estimate of the actual driving distance or time.

The unique function of the beam is an excellent example of how Microsoft Excel functions can be used to automate complex tasks in a simple spreadsheet formula. Calculating the time between the driving distance and the addresses, identifying the zips within the identified radius, individual functions are a very useful approach to analyzing the address and location information in Excel.
