Error message when appending data to CSV

[Evert_Randers]

Hi, I am using a simple Append to CSV activity, but suddenly I get this error message:

As nothing has been changed, what can cause this, and even more important, how to fix it?

Hi @Evert_Randers ,

Refer to the following thread, the issue seems to be same:

UiPath Excel Activities - CsvHelper error

Sub package CsvHelper is included in both UiPath.System.Activities and UiPath.Excel.Activities. It seems like this is causing error when appending a CSV, since the package is included twice with different version numbers. An easy solution would be to remove CsvHelper from UiPath.Excel.Activities? [image] message: Append To CSV: Method not found: ‘Void CsvHelper.CsvWriter…ctor(System.IO.TextWriter)’. level: Error

I missed that one. Thanks!
