Timed Subtitle Cue Review Sheet

Review every timed caption, identifier and setting in one ordered TSV from bounded SRT or ordinary WebVTT text.

Caption processing stays in this browser using the existing local worker. Runtime assets load by GET; no subtitle/media upload is part of this job. Originals/checkpoints retain the source content. Cleanup/Exit is not secure-erasure proof.

This flow needs JavaScript. If it does not load, refresh the page and try again.

About this flow

Paste caption contents or choose a UTF-8 TXT copy. Keep every cue field, order by original index/start/end seconds, and explicitly choose spreadsheet formula protection. Download the complete review sheet and retain the original caption document.

Limitations

One UTF-8 input up to2MiB and10,000 cues; positive durations and timestamps within seven days. Existing parser restrictions apply.
Each downstream JSON/CSV input remains bounded at5MiB; an expanded intermediate can stop the chain with a retained checkpoint. Final table writing remains bounded at20MiB.
All six cue fields remain present. Payload line endings normalize to LF; TSV records use quoted CRLF. Equal numeric keys stay stable.
Formula protection changes leading formula-like cell text. It does not change original/CSV checkpoint downloads or declare spreadsheet cell types.
Ordinary WebVTT only: no HLS timestamp maps, inline karaoke timestamps or SRT position extensions. This is not arbitrary standards conformance or a lossless caption-document converter.
No transcription, media rendering/playback, timing correction, synchronization, linguistic review or measured-demand claim.
