Office Tools

Office tools handle the everyday document conversions and edits that usually mean firing up Microsoft Office, paying for a desktop converter, or — worse — uploading a confidential file to an unknown SaaS. This category collects 27+ utilities for Word, Excel, PowerPoint and PDF that all run entirely in your browser. Nothing is uploaded, nothing is stored, and you don't need an account to use any of them.

The collection covers the conversions most people actually need: Excel ↔ CSV / JSON / XML / SQL, Word ↔ PDF / TXT, PDF ↔ Excel / CSV / Word / PowerPoint, and PowerPoint ↔ PDF / images. There are merge and split tools for every major office format (combine multiple Word documents, split a PDF by page range, merge several Excel sheets into one workbook, divide a PowerPoint deck), and extractor tools that pull text, images, or page counts out of any office file. CSV imports auto-detect encoding (UTF-8, Shift_JIS, GB18030, EUC-KR, Big5, Vietnamese) so files exported from Asian-language Excel installations don't turn into mojibake. PDF tools use pdf.js under the hood, Excel tools use SheetJS, Word and PowerPoint tools parse and rebuild the underlying OOXML zip. Everything stays on your machine — open the tool, drop the file, get the result.
