Subtitle & Transcript Format Converter

Convert .srt subtitle files into WebVTT (.vtt), plain text (.txt), JSON (.json), or Markdown (.md).

Format Decision Procedure

Walk this procedure based on target format:

Which format is requested?
├── Plain Text (.txt)
│   └── Strip all sequence numbers and timestamps. Join continuous paragraphs with single blank lines.
├── WebVTT (.vtt)
│   └── Add "WEBVTT" header at line 1. Replace commas in timestamps with periods (00:00:01,000 → 00:00:01.000).
├── JSON Array (.json)
│   └── Parse into structured array:
│       [
│         { "id": 1, "start": 0.0, "end": 4.5, "text": "..." }
│       ]
└── Markdown Transcript (.md)
    └── Group text into time-stamped sections [MM:SS] with formatted headers and clean paragraphs.

Quick CLI / Script One-Liners

For automated file conversions via Node/Bun or standard tools:

# Extract plain text from SRT using node/bun
node -e "
const fs = require('fs');
const text = fs.readFileSync('input.srt', 'utf8')
  .replace(/\d+\r?\n\d{2}:\d{2}:\d{2},\d{3} --> \d{2}:\d{2}:\d{2},\d{3}\r?\n/g, '')
  .replace(/\r?\n\r?\n/g, ' ');
fs.writeFileSync('output.txt', text.trim());
"
