Sending Serial Data from Excel? The scripting language is called Visual Basic for Applications. I think this is an great way to log the data coming from my Arduino.

Arduino Serial Data Directly Into Microsoft Excel Last Modified: November 28, 2016, at 010:16 AM By: dndubins Platforms: Microsoft Excel 2010 (Mac and PC versions) Although 3rd party applications and plugins are available for port logging, it is possible to log data directly into Microsoft Excel through Visual Basic. Link to worksheet: Introduction There are no lack of applications tailored towards saving a.CSV file from an open port, which can then be imported into Microsoft Excel. For instance,,, and are useful and implementable strategies. However, it is possible to have Visual Basic (underneath Excel) listen to the serial port and output the data directly into Excel without requiring another program or plugin to load - in both Mac and PC versions. The first order of business is finding out the open port number, through the Arduino IDE. This is done by loading the Arduino IDE, connecting your device (e.g.

Arduino Uno), then clicking on Tools --> Port. Visual Basic Macros For Excel in Windows: Next, you will need to create a macro in Visual Basic to read the port. In Windows, the stripped down core routine looks like this.

Visual Basic connects directly to the COM port. This version of the macro only prints a message of the data, rather than the spreadsheet. However, going to the spreadsheet from this format is easier with commands like: ActiveCell.Offset(1,0).Value = record_cat For Excel in OS X: For the Mac version of Excel, things are a little more complicated. The Open COMstring command won't work. However, Visual Basic allows for shell commands. One strategy then is to call the following command in a shell: head -1 /dev/cu.yourcommunicationsportgoeshere This gets the first line of your port from the terminal prompt. Then, since calling the head command will reset the serial connection each time, for the Uno it was necessary to connect a 10 uF capacitor between RST and GND.

Here is a stripped down version of the Visual Basic macro for Mac. Icare data recovery.

When you think about serial communications, Microsoft Excel isn’t typically the first program that springs to mind. But this spreadsheet has a rather powerful scripting language hidden away inside it, which can, with a little coding, be used to. The scripting language is called, and it has been a part of Microsoft’s Office suite since 1993.

Since then, it has evolved into a powerful (if sometimes frustrating) language that offers a subset of the features from Visual Basic. It can be a useful tool.

Imagine, for instance, that you are logging data from an instrument that has a serial port (or even an emulated one over USB). With a bit of VBA, you could create a spreadsheet that talks to the instrument directly, grabbing the data and processing it as required straight into the spreadsheet. It’s a handy trick that I have used myself several times, and [Maurizio] does a nice job of explaining how the code works, and how to integrate this code into Excel. If you’re looking for other ways to leverage this Excel feature, consider or building inside of your sheets.
