Binary.FromList

Binary

Converts a list of byte numbers (0-255) into a binary value.

Syntax

Binary.FromList(list as list) as binary

Parameters

Name	Type	Required	Description
`list`	`list`	Yes	A list of numbers (each 0 to 255) representing individual bytes.

Return Value

binary — A binary value created from the list of byte values.

Remarks

Binary.FromList converts a list of numbers into a binary value. Each number in the list represents a single byte and must be in the range 0 to 255. This is the inverse of Binary.ToList.

This function is useful for constructing binary data byte-by-byte, such as building custom binary headers or protocol messages.

let
    Bytes = {72, 101, 108, 108, 111},
    AsBinary = Binary.FromList(Bytes),
    AsText = Text.FromBinary(AsBinary)
in
    AsText

Applied Steps

Converts the binary value back to text, yielding "Hello".
