I'm excited to hear about your project! As a dedicated freelancer with extensive experience in data entry, design graphics, Office Suite, entry data, databases, web programming and corel draw, Photoshop and Canva I am confident that I can help you make the perfect spreadsheet containing words copied from 50 PDFs.
I understand from your description that you would like column A to contain the lesson number and column B to contain the list of words that appear in the box labeled "words to read and write." This should take just a couple of hours once you get the hang of it.
I have worked with many different types of files before such as Adobe Dreamweaver PHP MySQL HTML and more so if you give me this project it won't be a problem for me to complete it. Please feel free to reach out if you have any questions or would like me to provide any additional information about my skills or experience.
