Recently, Google updated the Chrome version whereby manifest for any Chrome Extension script has now to be;

manifest_version: "2.0"

We have a script which pulls information from a spreadsheet and creates an email template filling in the various information from the Google spreadsheet in the new email. Since the update to manifest_version: "2.0" we have been unable to make this script operate correctly.

When updating to manifest version 2 you must ensure that your manifest.json uses the correct code as some of the code from manifest version 1.0 has been updated. We have changed code such as;

- including 'manifest_version: "2.0"
- changing 'popup': 'popup.html' to 'default_popup': 'popup.html'
- transferring any inline javascript in the popup.html file to be run externally

Below is the code from the manifest;

  "name": "POTool",
  "description": "Google spreadsheet -> Gmail transfer PO data",
  "version": "2.0",
  "manifest_version": 2,
  "permissions": [
  "background": {
"script": "background.html"
  "browser_action": {
    "default_icon": "icon.png",
    "default_popup": "popup.html"
  "content_scripts" : [
	  "matches": ["https://docs.google.com/spreadsheet/ccc?key=[key removed]",
"js": ["content_script.js"]
  "options_page": "options.html"

I've removed the key for security purposes.

The process when the script worked was;

1. We clicked an icon beside the address bar
2. A user prompt appears asking us to select which row from the spreadsheet we wished to process
3. A new email would open up in a new window
4. All the data from the spreadsheet is incorporated in an email template

The process at the moment is;

1. We click an icon beside the address bar
2. A user prompt appears asking us to select which row from the spreadsheet we wish to processs
3. Nothing else happens.

Thanks in advance for your help.

When you are at step 3: nothing else happens. Press CTRL+shift+J and see if you're getting errors.

I don't think the extension would load if there's an error in the manifest.

Know you can always debug your extension's javascript code. Open a page which matches your 'matches' rule. Then press F12 Go to the sources tab.
Click on "content scripts" on the left. You likely have to press F5 now.

Now you probably see a few items in the list with random names like "jpfegmkjdsbmksfjl" or "mdslfkbfseofesa" and the like. Just open the tree, and 1 of those things will have content_script.js in there. From there you can debug line per line.
