DeepSeek AI-assisted development
The initial spreadsheet-editor prototype was generated with DeepSeek. The prototype was subsequently reviewed, renamed, modified, security-hardened and integrated into QuickConverterLab. AI-generated code can contain errors, so the public version should be treated as independent software maintained by QuickConverterLab rather than as a DeepSeek product or endorsement.
Microsoft trademarks
QuickConverterLab is not affiliated with or endorsed by Microsoft. References to XLSX/XLS or Microsoft Excel are used only to describe file-format compatibility. Microsoft and Excel are trademarks of the Microsoft group of companies. Microsoft logos and product icons are not used as QuickConverterLab branding.
