Turn an Office file into Markdown.

characters of Markdown
Markdown is the shape almost everything reads: a notes app, a wiki, a static site, a code repository, and the model you are about to paste a contract into. This turns a Word file, a spreadsheet, a slide deck, a web page or a CSV into it without the document leaving your device.
No, and this is the difference worth checking. Converters of this kind do the work on their own machines and say so somewhere in their privacy pages, because parsing Office formats server-side is easier. This page is static files with no endpoint to send anything to: open your browser's network panel while you convert, or disconnect from the internet once the page has loaded and watch it keep working.
Because almost everything reads it: notes apps, wikis, static sites, code repositories, and language models, which take it in fewer tokens than HTML and with the structure still visible. A document converted to Markdown is a document another program can actually work with.
No, and it says so by name rather than reporting a corrupt file. Those are the Word 97-2003 era formats, which are a different thing from .docx, .xlsx and .pptx rather than an older version of them. Open the file and save it in the current format, then convert that.
Each sheet becomes its own table under a heading with the sheet's name, in workbook order. A single-sheet workbook does not get a heading naming the only sheet there is.
No, and both are deliberate. Speech needs a transcription model that would have to be downloaded here or run on somebody's server, and fetching a link is a network request — the promise this whole site is built on is that it makes none. A converter that takes a URL is a converter with a server.
