How to convert STL to CSV

Convert EBU-STL to CSV online. CutConvert decodes the broadcast subtitle file — GSI header, TTI blocks, the whole Tech 3264 structure — and writes a spreadsheet of every subtitle with start, end, and text, for QC and review without broadcast software.

  1. Add your .stl file

    Drag the EBU-STL onto the drop zone. (Binary Tech 3264 .stl — not the Spruce DVD text format that shares the extension.)

  2. Convert to CSV

    Press Convert. Every subtitle becomes a row with timing and text.

  3. Download your result

    Download the converted file instantly — or a single ZIP archive when you convert a batch of files.

EBU-STL subtitles and CSV spreadsheet, explained

EBU-STL is the European broadcast deliverable — and like all deliverable formats, it is unreadable without specialist tools the moment someone just wants to check what it says. This converter decodes the binary STL (validated against published IRT reference files) into a spreadsheet: one row per subtitle, frame-accurate timing, clean text. For an editable subtitle file instead, the STL to SRT converter uses the same decoder.

EBU-STL (Tech 3264) subtitles decoded into a spreadsheet — timing and text in columns. It is free to start, encrypted in transit, and converts a whole batch into one ZIP — sign in when you need large, high-volume jobs.

STL to CSV FAQ

Which STL format is this?

EBU-STL (Tech 3264), the binary European broadcast subtitle format — not Spruce STL, the old DVD Studio Pro text format that shares the extension.

Is the decoding verified?

Yes — the STL decoder is validated against published reference subtitle files from IRT, covering the GSI/TTI binary block structure.

What lands in the CSV?

Start time, end time, and text for every subtitle. Styling and box positioning stay behind — a spreadsheet has no representation for them.

Can I edit the subtitles?

Convert to SRT instead with the STL to SRT converter — same decoder, editable output.

Questions, answered

Where are my files processed?

Your files are uploaded over an encrypted (HTTPS) connection and converted on CutConvert’s servers, then handed straight back to you as a download. We never sell or share your media.

Is it free? Do I need an account?

Small, everyday batches are free to convert. For large or high-volume jobs you’ll create an account and upgrade — which keeps the free tier fast for everyone.

What do I get when I convert multiple files?

Drop several files and you get back one ZIP archive containing every converted file. Convert a single file and you simply get that one file — no unnecessary ZIP.

Which formats are supported?

You can convert EDL to CSV; SRT and VTT subtitles to each other and to plain text; SRT, TXT, and DOCX/DOC transcripts to Premiere Pro transcript JSON; SRT to Avid Media Composer caption TXT; and Premiere Pro .prtranscript exports to SRT, VTT, or text — with speaker labels preserved. More post-production formats are on the way.

Can I pick a frame rate?

Yes. For EDL and Avid caption output you can choose 23.976, 24, 25, 29.97, or 30 fps, or let CutConvert auto-detect it from your source.
