I had been looking for a program that would allow me to 'type' my information on an application and THIS IS IT! Thank you SOOOO MUCH for this pdffiller!

9/15/16: Hard to find blank forms for completion, but questions are covered well by support folks. Default is yearly subscription, but support folks were able to convert to monthly subscription at desired level. Problem with changing previous form required upgrade to yearly business plan. The erase tool only works with upgraded plans.

This has been one of the best subscriptions I have purchased. I use it at least 3 times a week and it makes my life so much easier as a real estate agent.

I had some trouble at first (yesterday), but support was able to help. Now things are going smoothly on my end. It still remains to see how my signers interact with PDF Filler.

Great for my online classes! This has been a great tool for editing PDFs for my Anatomy class. The only problem is the "drawing" tool does not provide enough color options. It's very limited.

The product works I was able to fill forms and use powerful tools. They are not Adobe though and they charge nearly as much. The web sight interface was easy to use. They charge WANton much especially if you want the option to use it for only a short period of time.

It was free and it only cost me a lil… It was free and it only cost me a lil over a buck to save to my computer for first time purchase of the 30 day free trial

Very easy to use Very easy to use. Loved it. Struggled with editing sideways orientated text. Type replaced went a little wonky, it was for a quick edit to a a basic document, not an official presentation, in which case I might have required a more powerful editor.

The CONCATENATE function allows you to combine text from different cells into one cell. In our example, we can use it to combine the text in column A and column B to create a combined name in a new column.
Most often, you use concatenation in Excel to join such data as names and addresses, display time, and date.
For example, CONCAT(The, ,sun, ,will, ,come, ,up, ,tomorrow.) will return The sun will come up tomorrow.
The concatenation of two or more numbers is the number formed by concatenating their numerals. For example, the concatenation of 1, 234, and 5678 is 12345678. The value of the result depends on the numeric base, which is typically understood from context.
The CONCATENATE function in Excel is used to join different pieces of text together or combine values from several cells into one cell. The syntax of Excel CONCATENATE is as follows: CONCATENATE(text1, [text2], u2026) Where text is a text string, cell reference or formula-driven value.
Use CONCATENATE, one of the text functions, to join two or more text strings into one string.
