About our Document Tools
Move content between the formats you actually use. Turn CSV into JSON, Markdown into HTML, Word into clean text, spreadsheets into tables and back again. Built on Mammoth.js and SheetJS, these converters parse your files locally so structured data and formatting are preserved without ever exposing the contents to a remote server.
Every tool in this collection is free, requires no sign-up, and processes your data entirely in your browser. That means there are no uploads, no waiting, and no privacy trade-offs — ideal whether you are on a fast desktop connection or a phone with patchy signal. Browse the 32 document tools above, or use the search to jump straight to the one you need.
