Frequently asked
Why convert SBV to CSV?+
SubViewer / YouTube SBV is a minimal subtitle format YouTube's uploader accepts — comma-separated timestamps, no cue numbers. Comma-separated values is built for translation workflows and bulk editing in Sheets or Excel. Converting lets you take a file produced for one workflow and use it in the other without re-typing or re-timing anything.
Is timing preserved exactly?+
Yes. The converter only re-encodes the file structure — start and end times round-trip to within one millisecond.
Does any styling survive the conversion?+
Neither format carries styling, so there's nothing to lose. The text and timing transfer exactly.
Does this run on a server?+
No. The conversion is pure JavaScript running in your browser — files never upload anywhere. Works offline once the page is loaded.
