CHIRP

Baofeng UV-5R+ model, exported contents to CSV file, modified, saved, then attempted to import but reached error saying unknown file format.

Issue and workaround:
NOTE: For clarity, orig.csv refers to original exported .csv file and mod.csv refers to modified .csv file
Exported orig.csv
Copied orig.csv file to another location with name orig1.csv
Changed orig1.csv file and saved using OpenOffice Calc under mod.csv
Changed (not saved) both orig1.csv and mod.csv to a .txt file, viewed both orig1.txt and mod.txt in Notepad, and found that orig1.txt export used COMMA'S for delineaters and the SAVED mod.txt file used SEMICOLON'S.

Did an EDIT, FIND AND REPLACE, changed semicolons to comma's, saved the mod.txt, then manually changed file extension again back to .csv, imported successfully into program with only the following errors (11 total but only one shown, line numbers only changed, I believe this is not needed for the Baofeng radios):
Line 2: [duplex] `-0' is not in valid list: ['', '+', '-', 'split', 'off']

Hope this helps, perhaps could include this into the FAQ portion about Unable to import CSV until its fixed
Cheers
