DOC to Markdown

Why convert DOC to Markdown?

DOC and Markdown are both document formats: DOC is best for older Word documents (before 2007), Markdown for notes and documentation written as plain text.

What is a DOC file?

Microsoft Word Binary File

Developed By
Microsoft
Initial Release
1983
MIME Type
application/msword

The DOC extension refers to the proprietary binary file format used by Microsoft Word versions 97 through 2003. It is structured around the Object Linking and Embedding (OLE) Compound File Binary (CFB) format, acting as a file system within a file that manages streams and storages for text, formatting, scripts, and metadata. Unlike modern XML-based alternatives, DOC files store data in binary records, which can make parsing complex and prone to corruption if the binary headers are damaged.

How to open a DOC file

Microsoft Word remains the primary software for full-feature support of the DOC binary format. However, owing to its ubiquity, most third-party word processors including LibreOffice Writer, Apache OpenOffice, and Corel WordPerfect provide reverse-engineered support for opening and editing these files. Google Docs also offers import capabilities, though complex formatting utilizing legacy OLE objects may experience rendering shifts during conversion.

What is an MD file?

Markdown Documentation

Developed By
John Gruber
Initial Release
2004
MIME Type
text/markdown

An MD file is a plain text document containing Markdown, a lightweight markup language created by John Gruber and Aaron Swartz. The format uses non-alphabetic characters (such as hashes for headers and asterisks for emphasis) to define formatting syntax that is human-readable in its raw form and easily convertible to valid XHTML or HTML. It is the de facto standard for documentation in version control systems like Git.

How to open an MD file

As strictly plain text, MD files can be opened and edited in any basic text editor such as Microsoft Notepad or Apple TextEdit. For a rendered preview of the formatting, specialized editors like Obsidian, Typora, or Visual Studio Code are recommended.
