Converting a PDF to Excel can be done using various methods, and the effectiveness depends on the content and structure of the PDF. Here are a few approaches you can try:

1. Online Converters: There are several online tools that allow you to convert PDF files to Excel format. Websites like SmallPDF, Adobe Acrobat Online, or Zamzar provide such services. You usually upload your PDF, and they will convert it for you. Ensure you trust the site and review their privacy policy before uploading sensitive information.
2. Adobe Acrobat: If you have Adobe Acrobat (not the free Reader), you can export PDFs to various formats, including Excel. Open the PDF in Adobe Acrobat, go to File -> Export To -> Spreadsheet -> Microsoft Excel Workbook.
3. Microsoft Excel: If the PDF is simple and contains mostly tabular data, you can try directly opening the PDF in Excel. Go to File -> Open, choose your PDF file, and follow the prompts in the Text Import Wizard.
4. Copy-Paste Method: For simple tables, you can try copying the content directly from the PDF and pasting it into Excel. However, this may not work well for complex formatting.
5. Third-Party Software: There are various third-party software applications specifically designed for PDF to Excel conversion. Examples include Able2Extract, Nitro PDF, and PDF2XL. These tools often offer more advanced features and better handling of complex PDF structures.
6. OCR (Optical Character Recognition): If your PDF contains scanned images or non-selectable text, you may need to use OCR software first to convert the images into editable text. Once the text is recognized, you can then copy and paste or use other methods mentioned above.

Remember that the quality of the conversion depends on the complexity and layout of the PDF. Simple tables usually convert more accurately than complex, formatted documents. Additionally, manual adjustments may be necessary after conversion to ensure accuracy.
