that lets you import and export the lists to CSV files.

The CSV format is compatible with the Palm CSV format. The first column is the memo itself, the next is a 0 or 1 (0 = not encrypted, 1 = encrypted). The third column is a category. Currently, the second and third columns are simply ignored. Also, encrypted notes are not supported.
"This is my note",0,""
"This is another note",0,""

If you have the OI File Manager (or compatible) installed then you can select the file for import / export through the file manager.
You can also launch ConvertCSV from the file manager by clicking on a CSV file.

Be sure to specify the correct file name. If your file is located on the SD card, it has to start with "/sdcard/", for example "/sdcard/notepad.csv". It is more convenient to pick the correct file if you install OI File Manager.
