Script to remove all videos from Youtube Watch Later playlist

Remove videos from Youtube Watch Later playlist.md

UPDATED 22.11.2022

It's been two years since the last update, so here's the updated working script as per the comments below.

Thanks to BryanHaley for this.

setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

    video.querySelector('#primary button[aria-label="Action menu"]').click();

    var things = document.evaluate(
        '//span[contains(text(),"Remove from")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

    for (var i = 0; i < things.snapshotLength; i++) 
    {
        things.snapshotItem(i).click();
    }
}, 500);

Non-english users will need to change "Action menu" and "Remove from" to what YouTube uses for their localization.

this code worked....:)

Thanks worked like a charm! Had to translate the aria-label and text for dutch:

setInterval(function () {
  document.querySelector('#primary button[aria-label="Actiemenu"]').click();
  var things = document.evaluate(
    '//span[contains(text(),"Verwijderen uit")]',
    document,
    null,
    XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
    null
  );
  for (var i = 0; i < things.snapshotLength; i++) {
    things.snapshotItem(i).click();
  }
}, 1000);

Here's my take on this

setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

    video.querySelector('#primary button[aria-label="Action menu"]').click();

    var things = document.evaluate(
        '//span[contains(text(),"Remove from")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

    for (var i = 0; i < things.snapshotLength; i++) 
    {
        things.snapshotItem(i).click();
    }
}, 500);

Working as of 11/21/2022. Just let it run in the background. Non-english users will need to change "Action menu" and "Remove from" to what YouTube uses for their localization.

If you need it to clear hidden videos this is the tweak to do that (I had like 200) - click options menu and show hidden videos then run this

setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

    video.querySelector('#button > yt-icon').click();

    var things = document.evaluate(
        '//span[contains(text(),"Remove from")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

    for (var i = 0; i < things.snapshotLength; i++) 
    {
        things.snapshotItem(i).click();
    }
}, 500);

This is a lifesaver for me. Thanks.

Russian version

setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

    video.querySelector('#primary button[aria-label="Меню действий"]').click();

    var things = document.evaluate(
        '//span[contains(text(),"Удалить из плейлиста")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

    for (var i = 0; i < things.snapshotLength; i++)
    {
        things.snapshotItem(i).click();
    }
}, 500);

Swedish version:

setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

    video.querySelector('#primary button[aria-label="Åtgärdsmeny"]').click();

    var things = document.evaluate(
        '//span[contains(text(),"Ta bort från")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

    for (var i = 0; i < things.snapshotLength; i++) 
    {
        things.snapshotItem(i).click();
    }
}, 500);

YouTube appears to rate limit you after 200ish deletions in a short time - so while the deletions appear to work on the UI side, the videos aren't actually removed from the playlist. Absolutely infuriating.

Here's a modified version of the script that deletes 200 at a time, waiting 5 minutes between each batch to avoid doing any deletions that, uh, don't actually delete. With a 5000-video playlist, this should take 167ish minutes to run. Just put it on overnight or something.

function deleteVideoFromWatchLater() {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];
    video.querySelector('#primary button[aria-label="Action menu"]').click();
    var things = document.evaluate(
        '//span[contains(text(),"Remove from")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );
    for (var i = 0; i < things.snapshotLength; i++) {
        things.snapshotItem(i).click();
    }
}

async function deleteWatchLater() {
  // Fiddle with these if you'd like
  let batchSize = 200; // Number to delete at once before waiting
  let waitBetweenBatchesInMilliseconds = 1000 * 60 * 5; // 5 minutes
  let waitBetweenDeletionsInMilliseconds = 500; // Half a second

  let totalWaitTime = ((5000 / batchSize) * (waitBetweenBatchesInMilliseconds / 1000 / 60)) + (5000 * (waitBetweenDeletionsInMilliseconds / 1000 / 60))
  console.log(`Deletion will take around ${totalWaitTime.toFixed(0)} minutes to run if the playlist is full.`);

  let count = 0;
  while (true) {
    await new Promise(resolve => setTimeout(resolve, waitBetweenDeletionsInMilliseconds));
    deleteVideoFromWatchLater();
    count++;

    if (count % batchSize === 0 && count !== 0) {
      console.log('Waiting for 5 minutes...');
      await new Promise(resolve => setTimeout(waitBetweenBatchesInMilliseconds));
    }
  }
}

deleteWatchLater();

The batch sizes and wait times are guesses, but they worked for me. You may need to run this more than once if any rate limiting happens - just reload the page and run the script again.

There's the french version:

To launch it:

const watchLaterCleaner = setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

    video.querySelector('#primary button[aria-label="Menu d\'actions"]').click();

    var things = document.evaluate(
        '//span[contains(text(),"Supprimer de")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

    for (var i = 0; i < things.snapshotLength; i++) 
    {
        things.snapshotItem(i).click();
    }
}, 500);

To stop it (if you want to):

clearInterval(watchLaterCleaner);

works well! thanks a lot

It works like a charm! TIP: Disable display images on your browser settings, it runs smoother!

For Spanish from Spain users the code is:

setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

    video.querySelector('#primary button[aria-label="Menú de acciones"]').click();

    var things = document.evaluate(
        '//span[contains(text(),"Quitar de")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

    for (var i = 0; i < things.snapshotLength; i++) 
    {
        things.snapshotItem(i).click();
    }
}, 500);

It is awesome to finally see my list in a manageable size, thank you!

Nice

I made a version that allows one to remove only watched videos or all.
Simply change the <= 10 with your preferred progress bar (how much of the video you watched) threshold.

var counter = 0;
setInterval(function () {
    let video = document.getElementsByTagName('ytd-playlist-video-renderer')[counter];
    let progress = "0";
    console.log(video.querySelector('#video-title').innerText)
    if(video.querySelector('#progress') !== null && video.querySelector('#progress') !== undefined){
    progress = video.querySelector('#progress').style.getPropertyValue("width")
    console.log(progress)
    } else {
    console.log("not deleted");
    counter++;
    return;
    }
    video.querySelector('#primary button[aria-label="Action menu"]').click();
    
    var things = document.evaluate(
        '//span[contains(text(),"Remove from")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

if(parseInt(progress.substring(0, progress.length -1)) >= 50){
    console.log("deleted")
    for (var i = 0; i < things.snapshotLength; i++) 
    {
        things.snapshotItem(i).click();
    }
    } else {
    console.log("not deleted")
    counter++;
    }
}, 800);

This thread was a good reference when I need similar functionality (many thanks!), so I implemented it into a web extension. But my code was a little bare, and private extensions doesn't seem to be a thing, so just recently I converted it into a Userscript.

https://gist.github.com/AndersMoberg/0a9f996a49d7b3a9e9c01065ce29abf4

If you have a Userscript manager, press the Raw button and you should get the dialogue for installing it.
It only works with Swedish interface for now, but feel free to request your language if you'd like I can put it in.

Again, many thanks for this Gist and comment section

Still works, thanks!

It's giving off a "Uncaught TypeError: video.querySelector(...) is null" error and not actually doing anything.
