Adobe Photoshop Document (PSD) preserves non-destructive editing layers, masks, adjustment layers, and smart objects in a proprietary Adobe format. Office Open XML Spreadsheet (XLSX) stores cell values, formulas, formatting, and charts as zipped XML, the default format for Microsoft Excel 2007 and later. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard XLSX file readable by any compatible application. 1converter handles PSD-to-XLSX 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.
