How to convert SRT to Text with Regex and Javascript

Looking for a way to convert SRT files and texts (subtitles for movies, series and anime) into text using regex and javascript? This article will help you with this and other alternatives.

How to Convert SRT to Text with Javascript and Regex

To convert an SRT (SubRip Text) subtitle file to text using regex in JavaScript, you can use the following function:

function convertSrtToText(srt) { // Use a expressão regular para remover os números de linha e as marcas de tempo return srt.replace(/^\d+\n([\d:,]+ --> [\d:,]+\n)/gm, '');}

This function uses a regular expression to remove line numbers and timestamps from the SRT file. It returns the remaining text of the SRT file, minus the line numbers and timestamps.

To use this function, just call it passing the SRT file content as a parameter, as in the following example:

var srt = "1\n00:00:10,500 --> 00:00:13,000\nTexto da linha 1\n\n2\n00:00:13,500 --> 00:00:16,000\nTexto da linha 2\n\n3\n00:00:16,500 --> 00:00:19,000\nTexto da linha 3\n";var text = convertSrtToText(srt);console.log(text); // Exibe "Texto da linha 1\n\nTexto da linha 2\n\nTexto da linha 3\n"
