Frequently asked questions
Is my spreadsheet uploaded anywhere?
No. The file is read by your own browser and converted on your device. Nothing is sent to a server, so it is safe for internal or confidential data.
How big a file can it handle?
There is no fixed limit; it depends on your computer. Sheets with tens of thousands of rows work on a normal laptop. When the result is very large the live preview is replaced by a download button so the page stays fast.
What happens with several sheets?
Choose “All sheets” and each sheet becomes its own section with a ## heading and a table, all in one Markdown file. Or pick a single sheet from the list.
Are dates, percentages and currency kept?
Yes. Cells are converted as they are displayed in Excel, so 15-Jan-2026, 12.5% or ৳ 1,200 come out the same way, not as raw serial numbers.
What is “One block per row” for?
Wide sheets with many columns make very long table lines that are hard to read. This layout writes each row as a short list of “Column: value” lines, which is easier for people and for AI tools like ChatGPT and Claude to follow.
Does it keep formulas, colours or charts?
It keeps the result of each formula as it appears in the cell. Colours, charts and images are not part of Markdown, so they are left out.
