How to Use This Tool
Process many YouTube URLs with row-level errors and duplicate reporting. Extract unique YouTube video IDs from multiline URLs or IDs, flag invalid rows and duplicates, then copy or download a stable batch result.
The work this page finishes
Channel and campaign work often begins with dozens of mixed watch, short and share URLs; copying one ID at a time loses line provenance and hides duplicates. The row-preserving workspace makes a correction repeatable without rebuilding a prompt or transmitting the source file.
Deterministic workflow
Recognize an existing 11-character ID or extract it from common watch, youtu.be, embed and Shorts paths; retain row number, reject invalid input and emit each ID once. This page accepts at most 5,000 records and 2 MB of text; rejected items retain their row references while valid items remain available.
Why a dedicated interface helps
Use the unique list for an approved API request, spreadsheet join or embed inventory while keeping invalid rows visible for correction. Immediate recalculation and a stable export are useful when the same rule must be applied consistently across a list instead of explained one item at a time.
Assumptions
- YouTube video IDs contain 11 URL-safe characters.
- Each nonblank line contains one URL or one bare ID.
- Duplicate comparison is exact and case-sensitive.
Retain the original source until the destination accepts the result; processing stays in this tab, although the device and installed extensions remain part of the user's security boundary.
Limitations and review boundary
It does not fetch playlists, verify that a video exists, bypass privacy, download media or accept arbitrary non-YouTube URL formats. No supplied URL is requested and no pasted markup or code is executed; output is inserted through text-only DOM operations.
Verification and provenance
The implementation was checked against YouTube Embedded Players and Player Parameters on 2026-08-26, with fixtures for a known answer, an invalid input and a batch-specific edge condition. The four-row fixture yields two unique IDs, one invalid row and one duplicate row.
