What is a CDXML file?

CDXML files mostly belong to ChemDraw. CDXML files are XML-based files used to store chemical structure drawings.
They encode data for molecules, including atoms, bonds, and layout information, making them ideal for representing chemical diagrams.

They use XML tags to clearly define each element of the chemical structure.

They are the main format for ChemDraw, which is trusted by chemists to create, view, and share chemical structures.

You can check the file structure and validation rules on the ChemDraw XML DTD page.
FilExt.com tip: This format allows both direct editing in a text editor and professional rendering in ChemDraw.

How do you open CDXML files?

You need a suitable software like ChemDraw to open a CDXML file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your CDXML file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CDXML file directly in the browser:. Just drag the file onto this browser window and drop it.

CDXML format details:

To find out what program is needed to open CDXML files, you need to determine the file format. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below you will find our evaluation of the CDXML files:

As a file extension, CDXML isn't very common and mainly uses a defined CDXML format. The following file formats are most commonly found in CDXML files:

• 80% of all CDXML files belong to ChemDraw XML. The files are using the common file format XML. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files are text files and can therefore be read using a text editor. The files are often between 5 KB and 110 KB in size. This file type is new and state-of-the-art. Certain words are almost always found in the files, such as <?xml version="1.0" encoding="UTF-8" ?>, <!DOCTYPE CDXML SYSTEM "http://www.cambridgesoft.com/xml/cdxml.dtd" >, <CDXML, CreationProgram, Name, ChemDraw 19 and BoundingBox. These files are often associated with structure, chem, draw, structures, compounds, pepcalc, figure, potential and document.
• 1% of all CDXML files are PowerShell Cmdlet Definition XML files, which are based on the XML file format. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. CDXML files can be up to 16 KB in size, but are often around 5.7 KB - 16 KB.

All other CDXML files (19%) have no consistent format. The category is msft. Drag & drop your file here to see the file format and a preview of your CDXML file!
