What is a .qmd file?

File extension details and usage information

Quarto Markdown (.qmd) is an open-source scientific and technical publishing system built on Pandoc. It serves as the next-generation version of R Markdown, designed to be multi-language and multi-engine. A .qmd file allows users to combine narrative text written in Markdown with executable code blocks written in Python, R, Julia, or Observable. When rendered via the Quarto CLI, the code is executed, and its output (such as charts, tables, or computed values) is integrated into a final polished document. This format is highly popular in data science and academia for reproducible research, as it ensures that the data analysis and the reporting remain in a single source file. Quarto can transform these files into a wide variety of formats, including HTML websites, PDF reports, MS Word documents, ePub books, and interactive presentations. It supports advanced features like LaTeX equations, cross-references, citations, and complex layouts, making it a comprehensive tool for technical communication and automated reporting.

Can .qmd files be converted?

Options for saving or exporting this file to another format

In many cases, a .qmd file can be converted by opening it in compatible software and using an option such as Save As, Export, or Convert. The available output formats depend on the file type and the application used.

  • Use the original software that created the file when possible.
  • Check whether the application supports exporting to common formats.
  • Be careful with online converters when working with private, business, or sensitive files.
  • If conversion fails, the file may be corrupted, incomplete, encrypted, or not actually a .qmd file.

Frequently Asked Questions

Common questions about .qmd files

To open a .qmd file, use software that supports this file format.

  • VS Code
  • RStudio
  • Quarto CLI
  • Notepad++
  • Nova

Open the file in compatible software and look for options such as Save As, Export, or Convert. If no export option is available, the file may require a specialized converter or the original application that created it.

  1. Verify that the file extension is correct.
  2. Install or update compatible software.
  3. Try another application that supports this format.
  4. Check whether the file is corrupted, incomplete, or encrypted.

A file extension alone does not guarantee whether a file is safe or unsafe. Only open files from trusted sources, scan unknown files before opening them, and be especially careful with executable, script, archive, and document files.

File safety tips

Use caution with unknown files

Only open files from trusted sources. Before opening a .qmd file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
