how to stop CF returning booleans as YES / NO ?

If you need it to return a boolean, you can use booleanFormat()

```booleanFormat( value )```

Great to use if your values are also numeric and you want to represent any value other than 0 as `true`

not great if you don't know the format/type of the variable

If you are getting a yes or no, which is your question it will always work

Unless your version of CF does not have that function. Another option is you use a Ternary conditional operator

```{your condition} ? true : false;```

For instance, you can do
```value EQ "yes" ? true : false;```

should've been more specific. This is happening on deserializejson

You can also test the variable with IsBoolean() if you’re not sure it’s always going to have a value that can be converted to true/false

I mean I've got a way around it for now. But in my screenshot, if I were to do `IsBoolean(name)` which would return false, I wouldn't want false returned

just CF being stupid converting true / false to yes no

Yeah, cf marching to the beat of its own drummer there. You would only need the isboolean or the ternary operator if it’s possible for values other than true/false might be in the json. otherwise you can just convert it with BooleanFormat(value)

I wonder if that's really a writeDump() artifact.
Also, in most situations, for better and worse, cf thinks "yes" == true, so depending on what you're actually going to do, it may not matter.

I agree <@U01N5980QR3>, that is an issue with CF’s `deserializeJSON` function. In the end, when working with JSON, you should have a general idea of what you are receiving, expecting and/or supporting, so you build it into your logic. The extra step to make sure yes/no to true false is a pain and really might only be necessary based on what you want to do with that data. As <@U0R6WFD7S> stated CF treats yes/no as true/false, so if you are using this to update a DB record and you are passing the value as a query param for a bit field, or as an argument to a function expecting a boolean, it will work without an issue.

OTOH, if you're exporting to a non-cf system, you probably do need to fix this up, either in the export or the import.

Putting this in as an ER, can I get some upvotes?
