Can't edit converted Word or Excel file

Do one of the following:

• If the PDF file was created from a scanned document, make sure that OCR (Optical Character Recognition) was enabled when you converted the PDF file. OCR is enabled by default when you convert your files via the Export PDF services. However, that may not be the case for other mechanisms of creating PDFs.
• Place your cursor in the middle of the text block that you want to edit and then double-click to select a word in the text. Triple-click to select a paragraph.
  

Additional information

When you convert a PDF file to Word or Excel format, ExportPDF performs optical character recognition (OCR) on the PDF to convert image text to searchable/editable text. If  the PDF you're converting was created from a scanned document, OCR is necessary to convert the image text in that document to rendered text that you can select and edit in Word or Excel.
