To remove the time stamps from the YouTube video transcript, you can use a Node.js program that processes the input file line-by-line and writes the cleaned data to the output file. Here is an example of how you can achieve this using modern JavaScript (Node.js) and the readline and fs modules.

  1. First, make sure you have Node.js installed on your system. If not, download and install it from Node.js.
  2. Create a new JavaScript file, for example clean_transcript.js, and add the following code:
const readline = require('readline');
const fs = require('fs');
const inputFile = 'transcript.txt';
const outputFile = 'cleaned.txt';

const readInterface = readline.createInterface({
    input: fs.createReadStream(inputFile),
    output: fs.createWriteStream(outputFile),
    console: false

readInterface.on('line', function(line) {
    // Check if the line contains a timestamp using a regular expression
    const timestampPattern = /^\d+:\d{2}$/;
    if (!timestampPattern.test(line)) {
        fs.appendFileSync(outputFile, line + '\n');

readInterface.on('close', function() {
    console.log('File cleaned and saved as ' + outputFile);
  1. Save the file and open a terminal or command prompt in the same directory as the clean_transcript.js file.
  2. Run the program using the command:
node clean_transcript.js
  1. After running the program, you should see a message indicating that the file has been cleaned and saved as cleaned.txt. Check the cleaned.txt file in the same directory, and you should see the cleaned transcript without the time stamps.

The program reads the transcript.txt file line-by-line, checks each line against a regular expression to determine if it contains a time stamp, and if not, writes the line to the cleaned.txt file. When the process is complete, the program will display a message indicating that the cleaned file has been saved.
