Frequently Asked Questions
What input formats are supported by this table generator?
You can input raw CSV, tab-separated TSV, or structured JSON arrays of objects.
How does column alignment work in Markdown?
Using colons in header separators (:--- for left, :---: for center, ---: for right alignment).
Is my data uploaded when I use the Markdown Table Generator?
No. All processing runs entirely in your browser. Nothing is sent to a server unless you explicitly create a share link.
Does this tool work offline?
Yes. After the first visit, the PWA service worker can serve the page and run the formatter without a network connection.
What is the maximum input size?
Most tools accept up to about 5MB in the editor. Very large inputs are processed preferentially in a Web Worker and may download instead of filling the output pane.
