Downloaded my Twitter data. Aside from media folders and a readme.txt file, it consists entirely of .js files, e.g. tweet.js. The readme describes the contents as JSON files, but they contain javascript code. When I open the files in Firefox 66 (Windows 7) or a text editor, I get the raw code, with text content embedded in the code. How do I execute the scripts to get the formatted content in the browser, short of writing more Javascript code?

In Firefox, You can use the view-source: psuedo protocol.

Enter into the URL address bar:

I'm not getting this from a server, which is probably part of the problem. I tried this: view-source:C:\[some local folder names]\direct-message.js

Got a listing of the .js source code again,

What about entering the location of the file from your computer in Firefox's Awesome Bar, and hit Enter? What happens?

I get the source code. I apparently need for the browser to execute the js to produce a formatted document.

If you want rendered content then you need to open the main HTML file. This file should load the additional JavaScript and CSS files saved in the _files folder.

Did you save the page as "Web page, complete" ?

Can you attach a screenshot?

Twitter "support" sent me the media and some .js files. No html or css.

What instructions are in the readme file?

Hi jjr2, the zip file should contain a ton of content. Just to review what I did to test this -- I don't tweet but I have linked another site to my Twitter account, so Twitter has stored that -- here's what I did:

(1) Open Twitter settings, scroll to the bottom, use the button in"Your Tweet Archive" (screenshot #1, upper part)

(2) Launch the link in my email to get a download button, and save the ZIP file (screenshot #1, lower part)

(3) Extract the entire contents of the zip file to a new folder, which has a main index.html file (screenshot #2)

(4) Double-click the index.html file to open it in Firefox (screenshot #3)

Thanks for the help, guys. Finally harrassed Twitter support (after trying for around 2 years) into sending me a working archive. Don't know what that other mess was.
