JSON String Hider

World's Simplest JSON Tool

Free online JSON string hider. Just load your JSON in the input field and all strings in it (including object keys and values) will automatically get converted to JSON escape codes. In the tool options, you can choose between different escape formats, such as surrogate pairs (\uHHHH), raw hex bytes (\xHH), and Unicode code points (\u{HHHHH}). Additionally, you can minify the output JSON to make it even harder to read. Created for developers by developers from team Browserling.

᠎᠎᠎          Tool Options

Escaped String Encoding

Encode JSON strings into surrogate
pairs in the format \uHHHH or
\uHHHH\uHHHH where HHHH
represents the surrogate pair value.
Encode JSON strings into hex
bytes in the format \xHH, where
HH is a two hex digit value.
(Works in JavaScript only.)
Encode JSON strings into surrogate
pairs in the format \u❴HHHHH❵,
where HHHHH represents
character's Unicode code point.
(Works in JavaScript only.)

Object Key Hiding

Also apply string escaping
to object keys in JSON
objects.

Hex Case

Print uppercase hexadecimal
escape sequences (e.g., "\xHH").
Print lowercase hexadecimal
escape sequences (e.g., "\xhh").

Prettify Output

Add spaces to JSON for
improved readability.
Set the number of spaces
used for each indent level.
Add tabs to JSON for
improved readability.
Remove all extra whitespaces
and create compressed JSON.

What Is a JSON String Hider?

This tool hides (obfuscates) the contents of a JSON data structure by rewriting strings in it to JavaScript escape sequences. This process is also called obfuscation and it involves finding all strings in the given data and converting them into encoded strings, character by character. The available encoding formats include UTF8 surrogate pair encoding (works in JSON and JavaScript), hexadecimal encoding (works only in JavaScript), and Unicode code point encoding (works only in JavaScript). This conversion makes it difficult for humans to read JSON strings directly, thus hiding sensitive data from being easily snoopable while still keeping the JSON syntax valid and parsable. By default, the program replaces strings with escape sequences in array elements and object values, but in the options, you can enable the "Hide Object Keys" to also replace object keys. In the options, you can also choose between different encoding methods, such as "Use Surrogate Pairs" (format: \uHHHH or \uHHHH\uHHHH), "Use Hex Bytes" (format: \xHH), or "Use Code Points" (format: \u{HHHHH}). The hex byte format works with simple ASCII strings, while surrogate pair and code point formats work with Unicode data and emojis. Additionally, you can specify whether to print hexadecimal characters in escape codes in uppercase or lowercase. For the output formatting, you can change the JSON data structure indentation settings, which include using spaces or tabs, and also define the number of spaces per indent level. You can also make the output completely unreadable by minimizing the JSON output. In this case, a compact JSON version is created without extra whitespaces, thus making the JSON strings harder to decipher. Json-abulous!


JSON String Hider Examples

Hide Strings in a JSON Array

In this example, we hide the names of Canadian provinces in a JSON array that are represented as strings. We use the UTF8 surrogate pair encoding, where each character of the string is represented either as a Unicode code point (if it's in the Basic Multilingual Plane (BMP) with code point values from U+0000 to U+FFFF) or with a surrogate pair (if it's outside the BMP). As a result, the province data is presented in an encrypted format, making the JSON strings less readable to humans (but perfectly parsable to JavaScript interpreters).

[ "Ontario", "Quebec", "Alberta" ]
[ "\u004f\u006e\u0074\u0061\u0072\u0069\u006f", "\u0051\u0075\u0065\u0062\u0065\u0063", "\u0041\u006c\u0062\u0065\u0072\u0074\u0061" ]
Required options
These options will be used automatically if you select this example.
Encode JSON strings into surrogate
pairs in the format \uHHHH or
\uHHHH\uHHHH where HHHH
represents the surrogate pair value.
Also apply string escaping
to object keys in JSON
objects.
Print lowercase hexadecimal
escape sequences (e.g., "\xhh").
Add tabs to JSON for
improved readability.

Encode Values in a JSON Object

This example changes the encoding of values in an object containing information about a pet. The tool uses the hexadecimal encoding to convert each letter in each string into a hex code. It prints the hex bytes in lowercase in the "\xhh" format. The hexadecimal byte encoding only works in JavaScript, so to decode the strings, simply run the array through a JavaScript interpreter or enter it in the developer tools console. As the "Hide Object Keys" option is turned off, the object keys remain unchanged. The numeric values of objects also remain unencoded as there are no escape codes for numbers.

{ "animal": "cat", "breed": "Manx", "age": 3 }
{ "animal": "\x63\x61\x74", "breed": "\x4d\x61\x6e\x78", "age": 3 }
Required options
These options will be used automatically if you select this example.
Encode JSON strings into hex

HH is a two hex digit value.
(Works in JavaScript only.)

objects.
Print lowercase hexadecimal
escape sequences (e.g., "\xhh").
Add spaces to JSON for
improved readability.
Set the number of spaces
used for each indent level.

Hide Entire JSON Object

In this example, we obscure all strings in a larger JSON object containing arrays. We turn on the "Hide Object Keys" option to also encode object keys and choose the Unicode code point encoding format "\u{HHHHH}" (please note that this encoding format works only in JavaScript). Additionally, to further complicate the decryption of JSON, we minify the output JSON and eliminate all spaces.

{ "hobbies": [ "reading", "painting" ], "sports": [ "basketball", "swimming" ] }
{"\u{00068}\u{0006F}\u{00062}\u{00062}\u{00069}\u{00065}\u{00073}":["\u{00072}\u{00065}\u{00061}\u{00064}\u{00069}\u{0006E}\u{00067}","\u{00070}\u{00061}\u{00069}\u{0006E}\u{00074}\u{00069}\u{0006E}\u{00067}"],"\u{00073}\u{00070}\u{0006F}\u{00072}\u{00074}\u{00073}":["\u{00062}\u{00061}\u{00073}\u{0006B}\u{00065}\u{00074}\u{00062}\u{00061}\u{0006C}\u{0006C}","\u{00073}\u{00077}\u{00069}\u{0006D}\u{0006D}\u{00069}\u{0006E}\u{00067}"]}
