Frequently Asked Questions (FAQ)
How are line breaks inside Excel cells handled?
Line breaks inside cells are automatically converted to <br> tags. This preserves multi-line text within cells without breaking Markdown table structure.
Does Markdown support merged cells (colspan or rowspan)?
Standard Markdown syntax does not support merged cells. To create tables with merged cells, use HTML <table> tags (colspan/rowspan). You can also export to HTML format with this tool.
How do I change column text alignment?
Click the alignment icons (left, center, right) below the output area. The delimiter row (:---, :---:, ---:) updates across the entire table.
Can I convert Markdown tables back to Excel or CSV?
Yes. Click the swap button (⇄) or select the Markdown tab, paste your Markdown table, and copy the result in Excel (TSV), CSV, or HTML format.
Is my table data sent to external servers?
No. All operations run strictly within your browser. Confidential figures, personal data, and internal schemas remain entirely on your local device.
Can I paste data from Google Sheets?
Yes. Select cells in Google Sheets, copy them (Ctrl+C / Cmd+C), and paste into the input area. The tool detects TSV data and converts it immediately.
Is this tool free for commercial use?
Yes. It is completely free for personal and commercial projects without restrictions.
Can I build a table by typing directly on the keyboard?
Yes. Press the Tab key to separate columns and Enter for new rows. The Markdown table updates in real time as you type.
