Prepare your input
Use the labelled controls below to enter your values or choose a local file. Load the example first if you want to see the expected input format. For imported tables, use a single header row and check the column names before running the operation. Keep an unchanged copy of your source data.
Review the result
Run the tool and inspect its on-screen findings before downloading. Validation errors identify input that needs correction; a successful export means the operation finished, not that the source information was independently verified. Copy a text result, download the prepared file or print the document where those controls are available. Reset clears this workspace.
Important limits
The final chapter length needs the video duration; missing duration leaves that check unverified.
