Text.ToBinary(
text as nullable text,
optional encoding as nullable number,
optional includeByteOrderMark as nullable logical
) as nullable binary
About
使用指定的编码将文本值编码为二进制值。
-
text:要编码的文本。 -
encoding:(可选) 用于将文本转换为二进制文件的编码。 使用 BinaryEncoding.Type 来指定编码类型。 如果未指定此值,则默认值为BinaryEncoding.Utf8。 -
includeByteOrderMark:(可选) 确定是否应在二进制输出的开头包含字节顺序标记(BOM)。 设置为true以自动包含 BOM,否则设置为false。 如果未指定此值,则默认值为false。
示例 1
将文本编码为二进制文件,生成可查看的 Base64 字符串,然后将其解码回文本。
用法
let
originalText = "Testing 1-2-3",
// Default UTF-8 binary
binaryData = Text.ToBinary(originalText),
// Convert binary to viewable Base64 string
encodedText = Binary.ToText(binaryData, BinaryEncoding.Base64),
// Decode back to text
decodedText = Text.FromBinary(binaryData),
result = [
OriginalText = originalText,
BinaryBase64 = encodedText,
DecodedText = decodedText
]
in
result
输出
[
OriginalText = "Testing 1-2-3",
BinaryEncoded = "VGVzdGluZyAxLTItMw==",
DecodedText = "Testing 1-2-3"
]
示例 2
使用字节顺序标记(BOM)将文本编码为二进制文件,生成可查看的十六进制字符串,然后将其解码回文本。
用法
let
originalText = "Testing 1-2-3",
// Convert to binary with BOM
binaryData = Text.ToBinary(originalText, TextEncoding.Utf16, true),
// Show binary as hex to demonstrate presence of BOM (fffe)
binaryAsHex = Binary.ToText(binaryData, BinaryEncoding.Hex),
// Decode back to text
decodedText = Text.FromBinary(binaryData, TextEncoding.Utf16),
// Compare original text and decoded text
isIdentical = originalText = decodedText,
result = [
OriginalText = originalText,
BinaryHex = binaryAsHex,
DecodedText = decodedText,
IsIdentical = isIdentical
]
in
result
输出
[
OriginalText = "Testing 1-2-3",
DecodedText = "fffe540065007300740069006e006700200031002d0032002d003300",
DecodedText = "Testing 1-2-3",
IsIdentical = true
]
