I am enjoying using the software and finding it helpful completing my VAT forms, I wish you could tab along though from column to column rather than use the space bar. It's a good piece of software though.

What do you like best? It's super fast to upload a document and simple to navigate the website. Filling out your PDF couldn't be easier! What do you dislike? The point where you save your document could be a little easier to understand but because I've been using them for 7+ years, I've got a handle on it. For someone just starting may find it a tiny bit confusing. Recommendations to others considering the product: This is a great platform to turn your PDF forms to fillable forms! It's easy to use and the price is nominal! Totally worth it! What problems are you solving with the product? What benefits have you realized? It's so easy to use! Make any PDF fillable! I have a tiny bit of OCD and filling in a form by hand just doesn't look professional enough for me so converting those forms to fillable using PDFFiller is a must!

Great Customer Service Used the service on a free trial, was a positive experience but I didn't need it after I was done applying for apartments. Forgot to cancel after my trial and was charged for 2 months, contacted customer service on their live chat and was given the full refund within a minute! World class customer service!

I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.

Required or mandatory fields are form questions that must be answered by the user before the form can be submitted. The opposite of required fields are optional fields. And this is where users can choose whether to answer the form questions or not.
The bold fields mean the column header is required. If you are not going to populate an optional field for all rows in a data import file, it is best to omit that optional field entirely from the file. School_id, for example, cannot be included and left blank for all rows.
Mandatory fields are questions that must be answered before the form can be submitted. Mandatory fields are also called compulsory or required fields. The opposite of a mandatory field is an optional field. Optional fields are also sometimes called voluntary fields.
When you make a field required, people must enter an answer to the field in order to submit their entry. When someone tries to submit an entry without filling out a required field, we highlight the problematic fields and display an error message to let them know the field is required.
Mark optional fields, not required Most designers use asterisks to indicate the required fields. But it is necessary to stop, the research on the subject is clear, and it is already the case for quite some time, used asterisks for the required field is a common mistake.
HTML does not recognize required. There are JavaScript libraries used for form/field validation that look for required and other things like val_email, val_number, etc. But, HTML doesn't use any of these things on its own. In this case, you have to validate the data with JavaScript by yourself.
