Conversion report

Ready

Timing editor (line starts / ends)

Enter 00:12.34 or seconds (e.g. 12.34). Blank means unknown. Timing is attached to the JSON, not the original text.

Synthetic timings are fictional and should never be distributed as real synchronization. Re-import the original file to clear them.

Run every converter against this source

Each format exports from the same canonical song, then is re-imported and compared. Formats that require missing timestamps/notes are blocked, not fabricated.
