Line 29 – This is where we actually build the record for an individual ASCII value and store it in the asc collection.

The details of what this code is doing were covered in the last article. It’s this loop that will do the conversion of the ASCII value that we’ll be referencing later.

Lines 19-28 – We start a nested ForAll loop against our binaryDigits collection.

So we store the offset to know which set of records in our collection apply to which value. We store this because we cannot clear a collection within a ForAll yet we need to use it 255 times.

itbOffset is the current number of rows in the intToBinary collection.

This is the ASCII value and what we’ll be using in our binary conversion.

input is set to the number we get from the Sequence function.

This allows us to know what the “size” of the number will be without having to hardcode it.

firstDigit is set to the total number of rows in the binaryDigits collection minus one.

Lines 14-18 – Using the With function allows us to setup some local variables that we’ll be using in our other calculations.

Line 13 – We start a ForAll loop using the Sequence function to generate a temporary collection of 255 numbers starting at 1.

Line 12 – We need to initialize/clear our asc collection which is the actual collection we are building.

Line 11 – We are using a temporary collection ( intToBinary) to store results as we calculate the binary equivalent of the ASCII value.

This is because we only care about 255 characters (8 bits) but if you were looking to increase that range for your ASCII table you’d need to increase the size here as well.

Unlike the last article, we set the Sequence to have 8 records starting at 7 and decreasing by 1.

For our purposes, this is a necessary step to be able to get the binary values. The last article went into more depth about what these lines do.

Lines 1-9 – This is the same code we used previously to generate a collection of binary digits and their positional values (worth).

Let’s look at what’s happening line by line: I’ve setup a beautiful Canvas Power App with this screen:īinary ASCII Character Collection – Power Apps.txt

Later I’ll show you how to use the collection to get individual values. The first is the generation of a collection that will contain the values. To make this a little more understandable, I’m going to break this down into pieces. In our case, we need to go just a little farther and be able to get the binary equivalent of the ASCII value for a character so we’ll be combining Tim’s technique with our integer to binary conversion logic laid out previously. If that’s all you’re here for, then click on that link and you’re done. In this post, Tim lays out a method to generate a collection using the Char function against numbers 0-255 that can then be used to lookup the ASCII value and he does it all in a single line. Blarg!Ī quick search came across this excellent article by Tim Leung, Text – How to convert a character to its ASCII numeric value. But if you’ve been using Power Apps for very long you’re likely not surprised to learn that Power Apps has no equivalent function. Nearly every language that has this function has its reverse usually called something like Asc and you could call that with A and get 65.

You can literally use Char(65) and you’ll get A. If you know the ASCII code (value) for a character, Power Apps makes it very easy to get that character by using the Char function. As you have likely guessed (by the fact the I’m writing a whole post about it), this wasn’t nearly as straightforward as I had thought. So, I just figured I’d get the ASCII value for a character and then use my handy Integer to Binary conversion method to take care of it. I recently needed to get the binary value of an ASCII character (as you do). There’s no reason for this dog with a bowtie, but there’s also no reason not to have a dog with a bowtie Let’s do it!
