Hi,

I have a text that has been converted using ToBase64 and I am trying to convert it back to string. I am trying to use BinaryDecode with Base64 encoding to convert it but it keeps telling me that text must be valid binary object?
Please help!

Text was converted using toBase64 now I need to convert it back to text again.

I used toString(ToBinary(base64text)) to convert it back to text. My question was since CF documentation recommends using BinaryDecode instead of ToBinary, how do I use BinaryDecode? I was not able to figure it out.

<cfset myText = "This is my Unicode Text ğĞüÜıİşŞöÖçÇ">
<cfdump var="#myText#">

<cfset mybase64 = toBase64(myText)>
<cfdump var="#mybase64#">

<cfset myTextBack = toString(ToBinary(mybase64))>
<cfdump var="#myTextBack#">

This works.

Same thing with BineryDecode

<cfset myTextBack = toString(BinaryDecode((mybase64),'Base64'))>

Use BinaryEncode() not BinaryDecode()
stringData = BinaryEncode(toBinary(yourBase64Data), "base64")

Your question is confusing. Base64 text is a string. Do you mean you want to convert a base64 string back into binary? As BKBK mentioned, BinaryEncode will convert binary data to base64 and BinaryDecode will convert base64 back into binary. Do you understand the difference?

What I have seen that after getting the binary version you just need to use ToString to convert into string "text" format.

<cfset yourText = toString(toBinary(YourData64))>

ToString on it's own doesn't work, I can make it work with tostringToBinary(text)) but Adobe documentation recommends to use BinaryDecode instad of the ToBinary
