XLSX to NSVConverter — Fast & Free Online

Office Open XML Spreadsheet (XLSX) stores cell values, formulas, formatting, and charts as zipped XML, the default format for Microsoft Excel 2007 and later. NSV file (NSV) stores data in the NSV format. This converts the tabular data into a fixed-layout document suitable for printing or sharing. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard NSV file readable by any compatible application. 1converter handles XLSX-to-NSV conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
