Reset Udemy Progress

Last Updated: 09/30/2022

Step 1. Go to Udemy course in browser

Go to the course and have any video up. The following code relies on the right sidebar to be visible to uncheck all your progress.

Step 2. Open browser console

You can do this with ctrl+shift+j and making sure the console tab is selected for chrome/brave

For FireFox, use ctrl+shift+i and select the console tab

Step 3. Run code in browser console

Copy and paste this code in the console Hit the enter key to run

// Stores all unexpanded section headers, and clicks on the unexpanded section headers to expand them
const sectionEl = document.querySelectorAll("section[data-purpose='sidebar'] div.udlite-btn");
sectionEl.forEach((section) => {
  const isClosed = section.parentElement.querySelector("span").getAttribute("data-checked") !== "checked"
  if (isClosed) section.click()
});

// Stores all checkboxes on the page, and clicks on any checkboxes on that currently checked
const checkboxes = document.querySelectorAll("input[type='checkbox']");
checkboxes.forEach((checkbox) => {
  if(checkbox.checked) {
    checkbox.click();
  }
})

Note that your Udemy progress % will not update back to 0%. This is on Udemy's server's end, which I can't control. If you start going through the course again, having a few sections checked off, the percentage should update accordingly.

If this helped you and you want to show your appreciation, consider buying me a coffee ☺ https://ko-fi.com/johndinhdev

Thank you.

This is gold! Saved me a ton of time!

This works perfectly if you are playing the first video and then run it

So incredibly awesome. Thank you.

The code does not work for Udemy Business, and it does not work for me. I try to use both Firefox and Chrome.

})

Should be changed to this:

const sectionEl = document.querySelectorAll("div[data-purpose='curriculum-section-container'] button[aria-expanded='false']");
sectionEl.forEach((section) => {
section.click();
});

// Stores all checkboxes on the page, and clicks on any checkboxes on that currently checked
const checkboxes = document.querySelectorAll("input[type='checkbox']");
checkboxes.forEach((checkbox) => {
if(checkbox.checked) {
checkbox.click();
}
})

There's a correction folks... Udemy updated some of their CSS classes recently to a reduced format. Meaning " div.udlite-btn" is now "div.ud-btn" The new code is as follows. Just copy and paste this one.. It should work just fine:

// Stores all unexpanded section headers, and clicks on the unexpanded section headers to expand them
const sectionEl = document.querySelectorAll("section[data-purpose='sidebar'] div.ud-btn");
sectionEl.forEach((section) => {
const isClosed = section.parentElement.querySelector("span").getAttribute("data-checked") !== "checked"
if (isClosed) section.click()
});

// Stores all checkboxes on the page, and clicks on any checkboxes on that currently checked
const checkboxes = document.querySelectorAll("input[type='checkbox']");
checkboxes.forEach((checkbox) => {
if(checkbox.checked) {
checkbox.click();
}
})

Expand all sections by hand and run this :
const sectionEl = document.querySelector("section[data-purpose='sidebar']"); const checkboxes = sectionEl.querySelectorAll("input[type='checkbox']"); checkboxes.forEach((checkbox) => { if (checkbox.checked) { checkbox.disabled = false; checkbox.click(); } });

Awesome It works. Thank you so much. @SandorGyorgy

Thanks guys! It's real time saver!

Thank you so much.
I am new to programming and finding it fascinating..... :-)
Programming can do miracles...!

Working

Expand all sections

const checkboxes = document.querySelectorAll("input[type='checkbox']");
checkboxes.forEach((checkbox) => {
if(checkbox.checked) {
checkbox.click();}})

Mark as Complete

const sectionEl = document.querySelector("section[data-purpose='sidebar']"); const checkboxes = sectionEl.querySelectorAll("input[type='checkbox']"); checkboxes.forEach((checkbox) => { if (!checkbox.checked) { checkbox.disabled = false; checkbox.click(); } });

const sectionEl = document.querySelector("section[data-purpose='sidebar']"); const checkboxes = sectionEl.querySelectorAll("input[type='checkbox']"); checkboxes.forEach((checkbox) => { if (checkbox.checked) { checkbox.disabled = false; checkbox.click(); } });

It works for me!

However, please be mindful to expand all sections before running the script.

Awesome thank you.

Awesome thank you.

To open all sections:

$x("/html/body/div[1]/div[1]/div/div/main/div/div[2]/section/div[2]/div/div/div/div[1]").map(el => el.click())

To uncheck all checkboxes:

const checkboxes = document.querySelectorAll("input[type='checkbox']");
checkboxes.forEach((checkbox) => {
if(checkbox.checked) {
checkbox.click();}})
