A chemical file format is a type of data file which is used specifically for depicting molecular data. One of the most widely used is the chemical table file format, which is similar to Structure Data Format files. They are text files that represent multiple chemical structure records and associated data fields.
Chemical table file (CT file) is a family of text-based chemical file formats that describe molecules and chemical reactions. One format, for example, lists each atom in a molecule, the x-y-z coordinates of that atom, and the bonds among the atoms.

The XYZ file format is a chemical file format. There is no formal standard and several variations exist, but a typical XYZ format specifies the molecule geometry by giving the number of atoms with Cartesian coordinates that will be read on the first line, a comment on the second, and the lines of atomic coordinates in the following lines.

chemical file format Every InChI starts with the string " InChI= " followed by the version number, currently 1 . If the InChI is standard, this is followed by the letter S for standard InChIs , which is a fully standardized InChI flavor maintaining the same level of attention to structure details and the same conventions for drawing perception.
Chemical Markup Language (ChemML or CML) is an approach to managing molecular information using tools such as XML and Java. [1] It was the first domain specific implementation based strictly on XML , first based on a DTD [ 2 ] and later on an XML Schema , [ 3 ] the most robust and widely used system for precise information management in many areas.
MDL introduced specifications for chemical file formats, including the molfile (.mol), and structure/data file (.sdf) which were subsequently placed in the public domain and have become standards for representing structures in 2-D drawings and for transferring such information with associated data, for example identifiers, chemical names and substance properties.
Crystallographic Information File (CIF) is a standard text file format for representing crystallographic information, promulgated by the International Union of Crystallography (IUCr). CIF was developed by the IUCr Working Party on Crystallographic Information in an effort sponsored by the IUCr Commission on Crystallographic Data and the IUCr ...
