HTML (.html, .htm)

Registered MIME type: text/html
HTML markup language and file format.
Predominant language for the creation of web pages.
HTML is an acronym derived from Hypertext Markup Language.
Plain text format.
Describes the structure and aspects of the appearance of web pages.
First published in 1993 as an Internet Engineering Task Force (IETF) working draft.
Maintained since 1996 by the World Wide Web Consortium (W3C).
Most recent version is 4.01, published in 1999 as W3C recommendation.
International standard ISO/IEC 15445:2000.
Predecessor of XHTML.
  • Import fully supports HTML version 4.01.
  • Output from Export[..., "HTML"]conforms to the XHTML 1.1 standard.
  • Import gives a plain text representation of an HTML file.
  • Import extracts tabular data from HTML.
  • Export creates an HTML version of expr.
  • Export translates expr to HTML, saving the output in the specified directory.
  • Import["file.html"] returns a string, representing the textual content of the file as formatted plain text.
  • Export["file.html", expr] exports a notebook, a cell, a list of cells, or other notebook elements to HTML.
  • Export always creates a complete HTML document, and not merely a fragment of HTML.
  • The output consists of one or more HTML files and two directories, HTMLFiles and HTMLLinks.
  • Mathematica by default converts typeset expressions to GIF images when exporting to HTML.
  • Mathematica can export Tooltip and Hyperlink expressions to HTML, creating HTML image maps if necessary.
  • Import imports the specified element from an HTML file.
  • Import imports multiple elements.
  • The import format can be specified with Import["file", "HTML"] or Import.
  • Export creates an HTML file by treating expr as specifying element elem.
  • Export treats each as specifying the corresponding .
  • Export exports expr with the specified option elements taken to have the specified values.
  • Export uses rules to specify the elements to be exported.
  • See the reference pages for full general information on Import and Export.
  • Save Selection As exports the selected part of a notebook as a web page.
  • Save As exports an entire notebook as a web page.
"Elements"list of elements and options available in this file
"Rules"full list of rules for each element and option
"Options"list of rules for options, properties, and settings
"Data"textual and numerical content from HTML table and list elements
"FullData"full tabular content, including empty HTML table and list elements

"Source"raw HTML source as a single string
"Title"HTML page title
"ImageLinks"URLs of embedded images
"XMLObject"symbolic XML representation of the entire document
  • Import by default uses the element.
  • When importing a plain HTML document as , Mathematica will attempt to convert it to well-formed XHTML and import the resulting XML file.
"Notebook"a Notebook expression

"Expression"an arbitrary Mathematica expression
CharacterEncodingAutomaticraw character encoding to use when importing the file
"Numeric"Truewhether to import data fields as numbers when possible
  • Mathematica always uses the UTF-8 encoding when exporting to HTML.

"ConvertReverseClosed"Falsewhether to export reverse-closed cell groups
"Content"Falsewhether to export MathML content elements
  • Possible settings for are:
Automaticcreates a CSS stylesheet from the Mathematica stylesheet
Nonedoes not create a stylesheet file or inline CSS style
"file.css"uses a stylesheet file
  • The following settings can be given for :
"GIF"converts all typeset expressions to GIF
"MathML"converts all typeset expressions to MathML
"DisplayForm"converts all typeset expressions to ASCII approximations of their appearance
"InputForm"converts all typeset expressions to their InputForm
  • Allowed settings for and are:
Falsedoes not export closed groups
Trueexports all cell groups
"LinkedPage"exports each forward-closed group to a separate page
