Loving it so far. Wish the search for documents in their library was easier to find, but other than that, I've been very happy with ease and quality.

For my very first experience I was a little surprised it wasn't free when I already am an Adobe Pro in the Cloud user and pay monthly for that, but oh well.

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.

I went into your chat hoping to get… I went into your chat hoping to get answers to my inquiries regarding my account and why I couldn't locate what it kept telling me that I should be seeing. Kara was the second chat agent I messaged in this desire to find out what I was doing wrong... which is fine. The first agent was like an operator I assume... finding out what I needed exactly and then transferring me to the right team. Which happened really QUICKLY!! I am NOT used to any online chats actually being able to do anything as fast as this happened today! Much less get an agent that could actually help me... TODAY was the first in a very LOOOONG time! Kara was GREAT!!! She needs a raise and maybe a promotion. Thanks again, Kara!!! KUDOS to Kara!!! The one entity that I HAD dedicated my loyalty to (Best Buy) for over a decade... is now in my rearview mirror!!!! They are atrocious at helping anyone with anything online!!! The store employees have to go through the same phone number we do, so they're worthless! And corporate Best Buy... smh... I won't get ugly here, but just state that they were the final straw that broke the camel's back!! I will NEVER give them any more of my time or money!!! PDF Filler though... has been a nice change!!! Thanks again!!!

i app works well once you find the form you need. I'm having a problem creating new forms or updating existing ones with new information while saving the old ones.

Very easy to use Very easy to use. Could perhaps be upgraded by getting you directly to one point you'are looking for in you document (pdfiller only underline the searched element but don't bring you to it).

Good Good, but would be better if the cursor would line up exactly on each line with the line above. It's frustrating to have to manually line it up every time.
