Features & Guidelines
How the local rendering engine works
100% Private & Local
Unlike conventional online viewers, your files are NEVER uploaded to a server. We use WebAssembly and JS libraries to parse Excel and Word files entirely inside your browser's memory.
Smart Excel Rendering
Upload an XLSX file and instantly view all its sheets. The tool automatically detects multiple tabs and generates a top navigation bar so you can switch between worksheets smoothly.
Format Limitations
We support modern formats: .docx, .xlsx, and .pdf. Legacy binary formats like .doc (Word 97-2003) cannot be parsed cleanly in JS and are currently not supported.
