Short notes on opening Office files, tracker modules, and other formats — and on what stays in your browser.

• How to open tracker modules (XM, MOD, IT) in your browser
  Play XM, MOD, IT, and S3M modules online without installing a tracker. How Filelathe’s in-browser libopenmpt player works.
• View unknown file formats without installing software
  What to do when nothing opens your file. Filelathe invents a mini-app for unfamiliar formats like EDN, YAML, and niche exports.
• Private in-browser file viewing (what stays local)
  How Filelathe handles files in your tab, what may hit the API, and why that matters versus upload-to-convert sites.
• How to open a DOCX file without Word
  Open a .docx without Word or an upload. Filelathe reads the Word package in your browser — text and embedded images, free, no signup.
• View Excel files in the browser
  View .xlsx and .xls in the browser with no upload and no Excel install. The first sheet opens as a grid on your device. Free, no signup.
• Open PowerPoint online without Office
  Open a PowerPoint file online with no upload and no Office install. .pptx slides render in your browser. Classic .ppt is a text peek, not a slideshow.
