Work with a Numbers spreadsheet in Excel

About Converting Numbers to Excel
Numbers is Apple's spreadsheet application. Unlike Excel it treats a sheet as a canvas holding multiple independent tables, which looks better but translates awkwardly to the single-grid model every other spreadsheet program uses. When you need to move away from Numbers, the usual reason is simple: poor interoperability — the canvas model does not map onto excel's grid.
Converting your Numbers spreadsheet to XLSX solves that. XLSX is the modern Microsoft Excel format — a ZIP of XML that stores multiple sheets, formulas, charts and formatting. It is the standard for business spreadsheets. In practice you gain formulas, charts and multiple sheets and open xml standard. PrivConvert runs the whole Numbers-to-XLSX conversion in server memory and deletes your file the instant the XLSX is ready — nothing is stored, logged or reused.
When this conversion helps
- You need formulas, charts and multiple sheets
- You need open XML standard
- You need compact and robust
- Escaping a proprietary Numbers file for the open XLSX standard
- Sharing a Numbers spreadsheet with someone whose software expects XLSX
Tips for best results
- After converting, open the XLSX and skim the formatting — complex layouts occasionally need a small touch-up.
- Files up to 250 MB are supported, and you can batch-convert several Numbers files at once; each is processed privately and deleted immediately.
