SRT to TXT Converter

A command line tool and JavaScript library that extracts plain text from SubRip (.srt) subtitle files and creates draft SRT files from text.

Built by StageCaptions, browser-based live captioning software for live events, conferences, and broadcasts.

Usage

Convert SRT to TXT:

npx @stagecaptions/srt-to-txt input.srt output.txt

Create an SRT file from text:

npx @stagecaptions/srt-to-txt input.txt output.srt

TXT to SRT creates generated timestamps. It does not sync text to audio.

Control generated cue timing and length:

npx @stagecaptions/srt-to-txt input.txt output.srt --cue-duration 4 --max-chars-per-cue 90

Defaults:

• --cue-duration 3
• --max-chars-per-cue 80

TXT to SRT treats each non-empty line as cue text. Long lines are split into smaller cues using --max-chars-per-cue.

Install

npm install @stagecaptions/srt-to-txt

JavaScript API

import { srtToTxt, txtToSrt } from "@stagecaptions/srt-to-txt";

const text = srtToTxt(`1
00:00:01,000 --> 00:00:03,500
Hello world.`);

const srt = txtToSrt("Hello world.", { cueDuration: 3 });

Validation

import { validateSrt } from "@stagecaptions/srt-to-txt";

const warnings = validateSrt(srtText);
