pdfFiller scores top ratings on review platforms
I felt misled at first feeling I needed to purchase the pdf filler after I had already used it. The customer support team replied quickly and resolved my issue.
this program is the answer to all who work with osha 300 log; thank you so much. Mahalo, and Aloha.

With the exception of the scam you have going to get people to sign up for your service... (i.e., On a holiday I came into my office to get work done quickly so I could then spend time with my family. I was soo pleased with your service as it let me upload a document and seamlessly edit it for 2 hours and the peace of mind that everything was working properly as your program continually provided feedback saying that 'all changes have been saved'. Then when I finally finished, after triple checking my work and feeling thrilled that I could go celebrate the holiday and be with my family, I selected the big bright button that says, Done!. And only THEN, after 2 hours of work, did you tell me, there is an error and I need to sign up for your program. You should be ashamed of yourselves. I was so excited to tell other people about your program and how well it works. After being scammed, ripped off in terms of money and precious time, I won't be telling anyone about your service. If you prefer to keep me as a happy customer, perhaps you will find a way to make up for this inconvenience (e.g., give me a discounted membership, upgrade my membership, some other kind gesture?) and correct this misunderstanding that you are covertly enticing people to use your program with an inconsiderate scam. I'd love if you followed up with me about this survey. Thank you. Sarah
I needed to type on an older document and this program seemed like a good choice. Also, since I can pay month to month I can stop when I am finished with the paperwork and that was a nice option.
Great PDF editor!
Great!
PDFfiller is easy to use, powerful, and user-friendly. It has all the features I need.
I'd like to see more fonts so I can match the fonts on the PDF page.
Easy and time saving
I use it to fill out government and medical forms for personal reasons. It could be used for any form you might need to complete.
It's very easy to use and has tons of forms available. You can upload unique forms and it works great on those too.
I have had some issues finding forms I've completed.
This is a great program if you need this service. We needed it at one time, but did not realize we could do this on line. I would recommend it to anyone who is in the business of needing documents filled out, signed and delivered.
Great Customer Service
I signed up for the free trial and ended up not needing to utilize their services. I had thought I had cancelled it, but for some reason it never went through, so I ended up getting charged for the full year. I contacted their live chat and a representative named Anna was very helpful and got the refund processed right away. Thank you for being gracious and so helpful! I very much appreciate this company's customer service. I will definitely use them in the future! :)
Elisa stepped right into action and helped me with my accounting issue. It is so nice to be able to have an account services individual help a customer with ease. This is a very rare occasion especially during this pandemic. Thank you Elisa!!!!!

What causes Excel file size to increase?
It is also possible that changes in any macros attached to the workbook could have greatly increased the file size. Finally, if you changed the format used to save the workbook, then the file size can increase. Check to make sure that you are using the proper file format for the version of Excel you are using.
Why is my Excel file size so large?
Excel has a used range for every sheet in your workbook. The larger this is, the bigger the file size becomes. Especially in older files, even if cells are blank and have no formatting, Excel may be treating them inside the used range, leading to a larger file size for no reason.
