eCTDViewer
See inside any eCTD submission in seconds.
Browse and check eCTD v3.2.2 submissions right in your browser. Open a .zip or a folder and the full CTD tree is in front of you. Nothing to install, and your files never leave your computer.

Built by a publisher, for the checks you actually do.
The whole CTD tree
Expand modules 1 to 5, search for a document and open it next to the tree.
Sequence or current view
See one sequence on its own, or the current state of the application across every sequence loaded.
Lifecycle at a glance
New, replace, append and delete operations are marked, and you can step through earlier versions of a document.
Hyperlink and bookmark checks
Check links and bookmarks across a sequence in one click and jump straight to anything that needs attention.
Submission information
Regional administrative information and the backbone, shown formatted or as raw XML.
Built-in document viewer
Read PDFs with their bookmarks, fit to page or width, without leaving the viewer.
Your submissions stay on your computer.
eCTDViewer runs entirely in your browser. Documents you open are never uploaded, and the viewer is blocked from sending data anywhere. That makes it safe to use with confidential, pre-submission content.

Questions
Do I need to install anything?
No. Log in and open eCTDViewer in a current version of Chrome, Edge, Firefox or Safari.
Are my documents uploaded anywhere?
Never. The viewer reads the files on your computer inside your browser and is blocked from sending data out.
Which submissions can it open?
eCTD v3.2.2 sequences with US or EU style regional XML, from a .zip file or a folder. You can load several sequences to see the lifecycle across them.
Does it replace an eCTD validator?
No. eCTDViewer is a review aid for browsing and checking a submission. It is not validated software and does not replace an eCTD validator or the agency’s own validation.
How does the company plan work?
Buy it with your work email, then turn on access for your company’s email domain. Colleagues sign up with their work email and can open the viewer while the subscription is active.
Can I cancel?
Yes, anytime from your account page.
