What do you like best?
It offered me a complete fillable PDF forms using data from spreadsheets in a matter of minutes. It Kept all of my completed forms secure and organized in one folder and I could easily access them anytime from its desktop software or its mobile application. PDFfiller’s add-on for Google Spreadsheets spared me tons of time I would use filling out multiple forms with data from my Google Sheets by hand. PDFfiller instead allowed me to automate the entire process by quickly merging data collected from the spreadsheet’s cells with fillable fields in the forms. It also helped me to easily share completed forms with my teammates and colleagues directly from it instead of having to download and share on various platforms separately.
What do you dislike?
It's a bit slow and too many requirements to return to the dashboard to make a new order or start over. It's a little difficult to use and I didn't really find the editor interference convenient at all. Also if you're using it online you should have a medium to fast internet connection as it works terribly with slow connections and lags a lot.
Recommendations to others considering the product:
It helps you export spreadsheets into PDFs in secs and saves you all the effort and time you'd have to go through if you tried to do it manually. I totally recommend it.
What problems are you solving with the product? What benefits have you realized?
I personally use a lot and to solve many issues I go through with spreadsheets. I deal and work with spreadsheets very often be it for registration of events we organize in ASCE student chapter or for our technical work in construction filling in dimensions, quantities and/or areas. I would always face this problem when I have to export the spreadsheet in a PDF format as every time the pdf file ends up being incomplete and I lose a lot of my spreadsheet data because the spreadsheet has no size restriction as in PDF; Landscape A3 or Letter A4 sizes and even if it put all of the spreadsheet content in the PDF, the font size is becomes very small and unreadable. So I used this software ad ever since It became really super easy to export sheets into PDFs without losing any data and only with a few clicks.

The software could use some updating. It is not the easiest to edit the document. The app also kept crashing on me and I had to start all over again. It was very frustrating.

Great software Great software! Very easy to use and does just about everything you would want a PDF editor to do. The only issue I had was when replacing text the text box deleted the line the text was sitting on and I ended up with a break in the line. Other than that I highly recommend!

In addition, files are at your fingertips at any time with PDFfiller. I don't have to complain about PDFfiller, because it is surprisingly this software, well worth the investment.
