How do column alignments work in Markdown tables?

Markdown syntax uses colons in the separator line below headers: ':---' aligns text to the left, ':---:' centers text, and '---:' aligns text to the right.

Can I convert an existing CSV or spreadsheet into a Markdown table?

Yes! Click the 'Import' button, select CSV or TSV, paste your spreadsheet data, and Toolbox will immediately populate the interactive visual editor and generate GitHub-ready Markdown.

How does the Transpose feature work?

Clicking 'Transpose' swaps rows and columns, turning your horizontal headers into the first column and rotating your data matrix effortlessly.

What is the ASCII / Box-Drawing format?

The ASCII format converts your table into Unicode borders (┌─┬─┐), which looks clean in plain-text README files, code comments, and terminal CLI outputs.

Is my table data processed locally?

Yes. All table conversions, cell edits, and formatting occur 100% in your browser memory with zero server uploads.
