FIT SDK
Included with the FIT SDK is the FitCSVTool utility. FitCSVTool is a command line tool used to convert binary FIT files to readable text files. These files can be viewed in a text editor or spreadsheet application.
Converting FIT files to text files may assist with the debugging of applications that encode or decode FIT files. If a FIT file is not able to be properly decoded by an application, the text version of the file may uncover valid data that the receiving application was not expecting or it may reveal data that was not properly encoded by the source.
FitCSVTool can also be used to convert properly formatted CSV files to binary FIT files.
