File Formats for exporting data from PicoLog

The following methods are (to my knowledge) all possible ways of exporting data from PicoLog (*.plw) into another file format.

[Note: tabs are changed into spaces in this posting so more than one space represents a tab. Tabs are generally taken to be 8 spaces (for aligning)]

PicoLog > File > Save As > File Type: Comma Separated Value files (*.csv)
raw data saved as comma separated values (CSV)

Code:

<t_ms>,,<ch-a>,<ch-b>,<ch-...>
-=[example]=-
0,,1.007,0.499
10,,1.007,0.498
PicoLog > File > Save As > File Type: Text files (*.txt)
raw data saved as tab separated values (TSV)

Code:

<t_ms> <extra tab> <ch-a> <ch-b> <ch-...>
-=[example]=-
0 1.007 0.499
10 1.007 0.498

Spreadsheet > Write to disk > File Type: print files (*.prn)
similar output as TSV (above) but includes column lables, units and a blank line before data

Code:

Time <ch-a label> <ch-b label> <ch-...>
ms <ch-a unit> <ch-b unit> <ch-...>
<blank line>
<t_ms> <ch-a> <ch-b> <ch-...>
-=[example]=-
Time angle RF
ms V V

0 1.007 0.499
10 1.007 0.498

convert *.plw to text file using a free program outside of PicoLog
Siongboon posted the source code of her C++ code here in the forum.

I saw many needs for such batch conversion software.
I wrote for might own use and thought it might be useful to anyone.

At the time of writing this code hasn't been verified, but the lack of negative responses seems to indicate that it works.
I think it's best to keep discussion of the code to the original posting (here).

If you have any other ways of exporting raw data for post-processing add them here.
Hopefully some of you will find this information useful.
