Retrieves videos and their comments from a specified YouTube channel, and exports the results to CSV files, using PowerShell.
This script uses the YouTube Data API to gather video metadata and comments from a given YouTube channel. The script fetches all videos associated with the specified channel, retrieves comments for each video, and processes the data to include relevant details such as video titles, publish times, and comment details. The output includes two CSV files: one containing detailed video and comment information, and another containing only the comment texts. The data is sorted by video publish time and comment publish time.
