{"version":"1.0","type":"rich","title":"Add signature image to PDF","description":"This example shows a PowerShell script that converts Excel workbooks to PDF files and inserts a signature image into each one. It processes every .xls and .xlsx file in a specified folder, opening the first worksheet of each workbook. Using the Excel COM object, it places the signature PNG into cell D10 via the `Shapes.AddPicture` method, then exports the workbook as a PDF using `ExportAsFixedFormat`. The script relies on the Microsoft Office Interop Excel API and iterates through files with `Get-ChildItem`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-24e460e797ef469167e977511cae43b6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
