Software related to a single data format or software system should be listed in a category dedicated that data format or system if possible. For example:

• use data format specific categories (when available) for conversion to/from a particular data format, either listed by the source or the destination format depending on the focus of the software (e.g. Computers/Data_Formats/Markup_Languages/HTML/Tools, Computers/Data_Formats/Markup_Languages/XML/Tools, Computers/Software/Typesetting/TeX/Converters)
• use system specific categories for conversion software installed as a plug-in for a particular software system, possibly in a Plug-Ins subcategory
• use Computers/Software/Internet/Authoring/Converters for conversion of data and programs between different data formats and languages directly related to Internet technologies which are not more specifically addressed by other categories
• use Computers/Software/Globalization/Character_Encoding for character encodings conversion
• use Computers/Software/Document_Imaging for document imaging software converting paper documents to images or electronic document formats
• use Computers/Software/Fonts/Management_and_Tools for font format conversion
• use Computers/Software/Document_Management/Products for software systems which more broadly manage files of any type
• use Computers/Software/Globalization/Computer_Aided_Translation for translation between languages
• use Computers/Software/Graphics/Converters for graphics format conversion
• use Computers/Multimedia/Music_and_Audio/Software/Converters for music or audio format conversion

Where software accepts or outputs multiple data formats exceeding the scope of other categories, the site may be listed here. Sites for companies who offer both data conversion software and services should be listed in the parent category.
