Convert between every common file format — documents, images, video, audio, spreadsheets, and ebooks. Every converter on Toolspace runs entirely in your browser using WebAssembly, so your files never leave your device.
Every tool runs in your browser — files never upload anywhere.
Toolspace covers spreadsheet conversions (XLSX ↔ CSV, XLSX → PDF, XLSX → XML), data-format conversions (CSV ↔ JSON ↔ XML ↔ YAML), archive utilities, and specialty format transforms. All powered by SheetJS and native browser parsers.
No. Every conversion runs in your browser using SheetJS (community edition, MIT-licensed) and JSZip. Financial data, HR spreadsheets, and other confidential workbooks stay on your device.
Yes — up to about 500,000-800,000 rows depending on cell density. Excel's own maximum is 1,048,576 rows per sheet; browser memory becomes the real limit before then.
Cell data types and formulas are preserved for XLSX-to-XLSX operations. Cell styling (colors, borders) is preserved when the target format supports it. Charts survive XLSX → XLSX but are lost in text-only targets like CSV.
Yes. Export your Google Sheet as .xlsx (File → Download → Microsoft Excel), then drop it into any Toolspace conversion tool.
Split Excel is a favorite — it takes a multi-sheet workbook and produces one .xlsx (or .csv) per sheet, packaged in a ZIP for easy download.
