Improve Performance of the Excel Macros

Taking Microsoft Excel 2003 VBA courses is the initial step in adding new functionality for your spreadsheet projects. Yet it’s just the beginning. Efficient and effective macro programming takes experience and exercise to attain.

Listed here are a couple of tips to obtain recent, or otherwise-so-recent, graduates of Microsoft Excel 2003 VBA courses got going in the right direction.

Reduce Traffic Between Worksheets And Macros

Passing data both to and from cells around the worksheet for your macros is an extremely slow process. Minimizing this communication greatly accelerates macro function. Quite a few users, motivated to use techniques learned in Microsoft Excel 2003 VBA courses, use macros for straightforward calculations better handled by worksheet functions. This can be for readability with complex formulas. It’s simpler to know a macro name than the usual huge equation.

The issue is the greater readable macro option would be slower due to the communication overhead. In a tiny spreadsheet the rate difference is undetectable, however in a sizable project unnecessary macros can slow calculations lower dramatically.

Another facet of worksheet-macro traffic that isn’t always covered in Microsoft Excel 2003 VBA courses is the amount of read/write occasions. It’s considerably faster to see a block of the 1000 cells rather than read each cell individually. If your macro is functioning on a wide range of information, browse the range in first before looping with the data instead of looping and studying a cell on every iteration.

Avoid Worksheet Functions In Macros

Graduates of Microsoft Excel 2003 VBA courses frequently think it is is simple to use existing worksheet functions, from simple Max formulas to advanced statistical functions, instead of re-inventing the wheel. However worksheet functions are slow.

Most of this is actually the communication problem in the last section however sometimes the present function is just too complex for that macro designer’s needs. Excel functions are made to cover an array of options so contain many logic tests and additional code to pay for eventualities that the macro may never face.

Even built-in macro functions discussed in Microsoft Excel 2003 VBA classes are frequently less capable than merely doing the work yourself. If there’s a VBA function you utilize frequently, try speed tests to find out if it might be faster to go in equations directly rather.

Provide Feedback

A viewed spreadsheet never calculates. Sometimes your macros can be a marvel of efficient design, an excellent illustration of skills learned in Microsoft Excel 2003 VBA courses, but users may see it as being slow.

Whenever the consumer will have to hold back for over a couple of seconds, provide some type of feedback. An updating dialogue, a progress bar, or perhaps a status cell around the sheet are methods for you to provide the user some symbol of just how much remains done.

Don’t be concerned about predicting time left, however a percentage complete a minimum of lets the consumer decide whether or not to wait or get coffee.

Not everyone would be interested to learn new things. If you have this enthusiasm in you, then do prefer attending the excel macro courses where you would be given lot many challenging tasks to perform as part of course learning.
