The "lotw2csv" program converts an ADIF report file from ARRL's Logbook of the World (LoTW) to comma-separated value (CSV) format so that it can be read into a spreadsheet program like Microsoft Excel.

Version 1.3 of the program was released on 13 October 2012. Click on this link to download the program. Click on this link to see the Version History.

The program will only run in a Command Prompt under Windows.

Just extract lotw2csv.exe from the .ZIP - if you then type lotw2csv and get the usage message, you're OK.

To run the program, at a command-prompt, type:

lotw2csv <lotwreport.adi> [output.CSV]

Do not include the <> or [] characters.

The first parameter is the name of the LoTW report file you downloaded from the LoTW website. The second parameter is optional, it specifies the name of the output file. If the name is not specified, the name of the output file will be the same as the name of the input file, but with a .CSV extension.
