Hi, thanks for your reply
I already have my one minute .dat file updating in excel every minute and use that data for graphing etc.
And ive got another .dat file updating every 250ms live data.
That data (a single string with wind, winddirection, temperature, humidity, solar, barometer etc.) i want to be shown in just a single cell in the same excel workboo/sheet as the one minute updating file already working.
So for example windspeed in cell A1, winddirection in A2 or B1 and so on.
Not appending, just updating in its own cell.
