What is a JDX file?

JDX files mostly belong to ChemDraw.

JDX files are mostly used as chemical data files in the JCAMP-DX format. They store spectral information from chemical analyses, such as infrared or NMR data. These files are text‐based and follow a standard that makes data exchange easier.

Below are the key uses of JDX files:

Chemical Data: some of these files contain JCAMP-DX spectral data. They are commonly used with software like ChemDraw and dedicated JCAMP viewers. See more at PerkinElmer.

Video Data: A small portion are used in a video file format associated with JDownloader.

Japanese Dictionary: some are formatted as Japanese dictionary files, used with specialized viewers.

Java XML Data: some are Java decompiled XML files, used by some developer tools.

FilExt.com tips: To open a JDX file, use the appropriate application for its content. While chemical files are best handled with JCAMP-DX compatible software that can graph spectral data, other variants may require video players or language tools. A text editor can reveal the file’s structure, but for graphical interpretation, a specialized viewer is advised.

How to open JDX files

You need a suitable software like ChemDraw to open a JDX 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 JDX file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a JDX file directly in the browser:. Just drag the file onto this browser window and drop it.

J Database Exchange (JDX) (O/R Mapping Specification) by Software Tree, Inc.
JDX provides a solution to object-relational mapping; one of the most complex issues to address in modern application architectures. JDX solves the problem of persistence for Java/J2EE applications.
JCAMP (Chemical Spectroscopic Data Exchange Format) by MDL Information Systems, Inc.
The Mime types used with this association are: chemical/x-jcamp-dx. The identifying characters used for this association are - Hex: 23 23 54 49 54 4C 45 3D, ASCII: ##TITLE=.
JSpell (UNICODE Dictionary) by Page Scholar Inc.
JSpell is a spell checker component for Web applications and Java-based applications. The JDX extension indicates a JSpell compatible file when the first part of the file name is LEX_ followed by a two letter language code and a two letter country code. For example, LEX_ENUS.JDX. This extension has been in use for JSpell since 1996. This file format is classified as Database.

JDX file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. 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. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. When there is a problem with a file, the first step to solving it is to determine the file format. In the following you will find our evaluation of the JDX files:

JDX is a very common file type and is mainly used by one program with a specific format. The two most common formats are as follows:

85% of all JDX files belong to JCAMP-DX format. These files are text files and can therefore be read using a text editor. JDX files are between 830 bytes and 160 KB in size. It is a modern file type. The files contain the following words: TITLE, OWNER, ORIGIN, ##JCAMP-DX=4.24, CLASS, Collection, copyright, Mass and ##DATA TYPE=INFRARED SPECTRUM. Such JDX files store data about mass, spectrum, predicted, chem, uvvis, distillation, spectra and codename.
4% of all JDX files use the same file format, which can be identified by the letters "01 00" at the beginning. They consist of illegible, cryptic characters. A typical file size is 430 KB. The keywords avc1 are typical for these files.

All other JDX files (11%) have no uniform format. These files are often connected to grignard, laser, temp, unknown, simple, fractional, acetone, product, water, data or spec. If you want to find out what your JDX file contains, drag and drop it onto this page.

How to solve problems with JDX files

Associate the JDX file extension with the correct application.
Update your software that should actually open text-based data files. Because only the current version supports the latest JDX file format. Search, therefore, e.g. on the manufacturer website after an available ChemDraw update.
To make sure that your JDX file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
