Automated YouTube Transcript Extraction Workflow

This n8n workflow automates the process of extracting and cleaning transcripts from YouTube videos. It begins with a webhook trigger where users submit a YouTube video URL. The workflow then makes an API request to retrieve the video’s transcript, processes and formats the transcript text for readability, and finally provides a cleaned transcript that can be used for various purposes such as content repurposing or documentation.

Step-by-step, the workflow starts with the Webhook node collecting the YouTube URL input. The URL is then sent via an HTTP request to an external transcript API (via RapidAPI), which returns the transcript data. The data is processed in a function node to extract and concatenate the transcript segments, handling different API response formats. The transcript is cleaned to improve readability, removing unnecessary spaces and fixing punctuation. The final cleaned transcript data is then stored in a Set node, ready for further use or output.

This workflow is useful for content creators, educators, or marketers who regularly need to extract and refine YouTube transcripts for content repurposing, analysis, or accessibility improvements.
