"Type information" when exporting or converting to CSV This topic contains 2 replies, has 3 voices, and was last updated by Don Jones 11 months, 3 weeks ago. Author Posts August 29, 2016 at 2:33 pm #52361 Tim CurwickParticipant By default, Export-CSV and ConvertTo-CSV prepend type information to the result. "Information" in this case meaning just the name. Is this useful for anything? Does anyone use it? Does anyone intentionally not use -NoTypeInformation ?

There's some ETS tie-in as well, although I don't think I've ever seen an example of that being actually practical or beneficial. Author Posts You must be logged in to reply to this topic.
