About this tool: Markdown Previewer
Preview headings, emphasis, lists, links, code, blockquotes and simple tables using a safe renderer that treats raw HTML as text rather than executable markup.
It is intended for development and data-cleanup workflows, with errors kept inside the interface so malformed input does not crash the page.
Markdown Previewer is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.
How it works
A lightweight parser recognizes common block and inline Markdown patterns and renders React text/elements. Links are allowed only for safe HTTP(S) or mailto targets; raw HTML is not passed through dangerouslySetInnerHTML.
Practical example
Write **important** to preview bold text, or add a pipe-delimited header/separator pair to preview a simple table.
Important notes
Validate the output in the context where you will use it, especially when the source data is incomplete or uses an unsupported syntax variant.
Privacy & processing
The primary formatting, parsing, encoding or conversion logic for this tool runs in the browser in the current build.
