Overview

In the maker's words.

EditXLSX (Edit Excel Online) is a browser office editor built around a WASM OpenXML engine. Open real .xlsx workbooks in the tab with formulas, multi-sheet references, and native fidelity — no desktop install. The same suite covers Word (WYSIWYG .docx) and PowerPoint (16:9 text and shape tweaks). PDF fill & sign is coming soon. Supported formats today: XLSX, DOCX, PPTX, PDF, CSV.

Sign in with Google or email OTP. Free accounts keep up to 10 files in the This-device library; editing runs in the browser, and local mode does not upload files for editing. After the editor is cached, you can keep working offline on local files. Pro unlocks Cloud storage (up to 1000 files per library); Pro+ removes the file caps.

Built for zero-install everyday Excel edits — not a full VBA/Power Query replacement. Pricing: Free · Pro $5/mo · Pro+ $10/mo.
