Hi @hank00000,
Welcome to the RStudio Community Forum.
Does the output file you expect to see show up if you run dir()?
The write_xlsx() function can only export dataframes (not tables). If you do have a table, you will need to convert it to a dataframe first (see ?as.data.frame). However, you said that you don't see an error (which you should see if you try and write a table) so maybe you can post part of the Guilds object and the code used to produce it so that folk here can provide further diagnosis?
