Frequently Asked Questions

How does Markdown table alignment work?

The formatter calculates the longest text string in each column across all rows and pads shorter cells with spaces, creating perfectly aligned visual columns.

Does this tool support GitHub Flavored Markdown (GFM)?

Yes. It fully supports GFM extensions including task list checkboxes, strikethrough, tables, and fenced code blocks.

Are my unpublished articles uploaded to any server?

No. Formatting is executed entirely in your browser client.

Can I copy the formatted Markdown or download it as a .md file?

Yes. Softnag provides both a one-click copy button and a direct .md file download.

Will formatting alter my code snippets inside code blocks?

No. Content inside fenced code blocks (```) is preserved exactly without unintended modifications.

Does table alignment change how Markdown renders on GitHub?

No. Aligned tables render identically in HTML, but make raw Markdown source files significantly easier to read and edit in code editors.
