I don't know how an oscilloscope saves a csv data to the usb stick, so i have to guess. They mostly open the csv file in excel, so no one even knows how its written, no one opens it with a text editor, though it's a text file. The thing i may be missing, are the numbers there in quotation marks, or not. Of course it can be opened in excel, then a column copied to Trinket, though i feel it's like a kind of banal way. In any case the first two rows are likely header, and must just be omitted.

As i have seen, it's time in seconds and voltage in volts, both float numbers in the exponent form. I don't know why so, i think the time column can just be ignored, as the samples are all after regular intervals, check it, but it's almost certain. All that is necessary for the list, is the second column.

There should be only two ways how csv can be written, without quotation marks and with quotation marks. The following are the trinkets to extract the second column in both ways.

Because the unit already is volts. And write the y scale just 1. The x scale, when the time column is omitted, should then be the time interval between samples in us. The samples there are float as well, otherwise scale is float, and only multiplying by float makes it float.

Yes all the calculations can be done in excel the same way as in Python, you see how, and there may be a precision problem as i said. Oh well, the lame excel, but do it if you want it so. I still consider the standard to explain things, is Python. One can make a mistake in Python, where all variables are named, it is difficult to make it faultless in python, but then what about excel with its totally not intuitive a3, b4 stuff.

Tell me excel, or maybe tell me matlab. And then you effectively do it so that i cannot say anything at all. Because in what should i talk then, excel or matlab or python? I don't understand why in hell they recommend to open these csv files in excel, people for whom precision should be so important. Excel is not proper for that purpose at all.

Paste your csv file somewhere? It's a text file as i said. Or paste it into a Trinket input.txt, and post the trinket here

Then i can write a script to extract data from it in an instant.

And how you likely did guess, i should post these two trinkets here, yet again. Why in hell i had to convert the input to int, there was no need to, all works the same when it's converted to float.

Trinket for the input part.
