Frequently asked questions
- What happens to rowspan and colspan?
- Their values repeat into every covered cell to form a rectangle. Associations remain, but the original merged presentation does not.
- Can scripts or formatting in the HTML execute?
- No. The converter extracts displayed cell text, and the preview is built safely from validated Table JSON.
- Can I convert multiple tables at once?
- No. Provide exactly one table element per input.
