TraceXLL logs all communications between Excel and XLL add-ins, e.g. the registration of worksheet functions, callbacks from your add-in to Excel and of course the invocation of add-in functions and commands. You can even diagnose third-party add-ins as you do not need to modify source code or recompile your project. Read more:
TraceXLL is using our Excel libraries to intercept calls and log arguments and results. The same library can be used to e.g. implement caching or argument checking for third-party XLLs.
Generally, not. The library can be used to inject fraudulent code that can not be detected by available spreadsheet auditing tools (think of "correcting" e.g. option prices calculated by a third-party add-in). If you have a legitimate use, contact us.
