TSV vs SRT: Format Comparison
Key differences between the two formats
| Feature | TSV | SRT |
|---|---|---|
| Purpose | Storing tab-separated TSV data | Timed text tracks for video |
| Structure | Tabular rows and columns | numbered cue blocks separated by blank lines, comma-separated milliseconds |
| Timestamp format | Flexible (HH:MM:SS, seconds, milliseconds) | HH:MM:SS,mmm --> HH:MM:SS,mmm |
| Native player support | Not directly playable | Plays in Premiere Pro and most subtitle tools |
| Editing | Edit in Excel TSV exports | Edit in subtitle tools or text editors |
| Best for | Authoring or exporting subtitle tables | Delivering captions in Premiere Pro |
| Encoding | UTF-8 recommended | UTF-8 (specification requirement) |
When to Convert
Common scenarios where this conversion is useful
Subtitle pipeline output
Take a TSV file produced by a transcription team or speech-to-text export and turn it into a clean SRT ready to drop into Premiere Pro.
Accessibility compliance
Convert TSV caption data into SubRip (SRT) subtitle files for WCAG 2.1 and ADA video accessibility, including educational and government content.
Localization handoff
Translation teams often deliver subtitles in spreadsheet form. Convert the final TSV into SRT files, one per language, for video distribution.
Course and webinar captions
Transform internal training transcripts kept in TSV into SRT captions for LMS platforms, webinar replays, and on-demand course videos.
How to Convert TSV to SRT
-
1
Upload your TSV file
Drag and drop your TSV (tab-separated values) file onto the converter, or click browse. The file is sent over an encrypted HTTPS connection.
-
2
Server-side conversion
The server parses your TSV with start, end, and text columns separated by tabs, then writes a valid SubRip (SRT) file with proper HH:MM:SS,mmm --> HH:MM:SS,mmm timecodes.

Download the SRT file
Save the resulting .srt file. The server copy is auto-deleted after processing. Drop it into Premiere Pro or any tool that accepts SRT subtitles.
Frequently Asked Questions
Provide a TSV (tab-separated values) file with start, end, and text columns separated by tabs. Header names like start, end, text or in, out, dialogue are auto-detected. The first sheet/row layout is used.
HH:MM:SS, HH:MM:SS,mmm, HH:MM:SS.mmm, plain seconds (with decimal), and millisecond integers all work. The converter normalizes them to the target subtitle format automatically.
Yes. The output follows the SubRip (SRT) specification: numbered cue blocks separated by blank lines, comma-separated milliseconds. It validates in standard subtitle tools and plays in Premiere Pro without further editing.
Yes. The SRT output drops directly into Premiere Pro, Final Cut Pro, DaVinci Resolve, VLC, YouTube uploads. No rewrapping or post-processing is required.
Uploads run over HTTPS, processing happens on a secure server, and files are deleted as soon as the converted result is returned. No data is retained.
Yes. There is no signup, no credit card, and no per-conversion charge. The converter is rate-limited per IP to keep the service available for everyone.
The converter writes cues in the order they appear in the TSV file. For best results, sort by start time before uploading. Overlapping cues are emitted as-is and rendered by the player.
The upload limit is 50 MB. That is enough for several hours of subtitle data — even feature-length captions are typically well under 1 MB.
Yes. Save the TSV input as UTF-8 (default in most tools) and the SRT output preserves Cyrillic, Arabic, CJK, accented Latin, and emoji characters.
Yes. Include a speaker column in your input and the converter prefixes each cue with the speaker name. For richer styling in SRT, edit the resulting file in a subtitle editor after conversion.
