TikTok Transcript Generator

Overview

This automated workflow extracts transcripts from TikTok videos by reading video URLs from a Google Sheet, calling the API via TikTok Transcript Generator, cleaning the subtitle data, and updating the sheet with transcripts. It efficiently handles batches, errors, and rate limits to provide a seamless transcription process.

Key Features

• Batch processing: Reads and processes multiple TikTok video URLs from Google Sheets.
• Automatic transcript generation: Uses the TikTok Transcript Generator API on RapidAPI.
• Clean subtitle output: Removes timestamps and headers for clear transcripts.
• Error handling: Marks videos with no available transcript.
• Rate limiting: Implements wait times to avoid API throttling on RapidAPI.
• Seamless Google Sheets integration: Updates the same sheet with transcript results and statuses.

API Used

• TikTok Transcript Generator API
