JSON Biçimlendirici Nedir?

JSON biçimlendirici, dağınık, biçimlendirilmemiş JSON verilerini doğru girintili ve satır sonlarıyla temiz, okunabilir bir formata dönüştüren bir araçtır. Ayrıca JSON'unuzun sözdizimsel olarak doğru olup olmadığını da doğrular.

Essential Uses of JSON Formatting

  • Debugging API Responses: When calling REST APIs, responses are often minified (no whitespace, single line). Formatting these responses makes them readable for debugging. For example, a minified API response {"user":{"id":123,"name":"John","roles":["admin","editor"]}} is hard to parse visually. Formatted with indentation, the structure becomes clear. You can see the nested user object, the id and name fields, and the roles array. Essential for verifying API behavior, inspecting nested data, and debugging integration issues.

  • Analyzing Log Files and Error Messages: Application logs, error messages, and monitoring systems often output JSON. These JSON blobs are typically minified and difficult to read. Formatting log JSON helps you understand error context, trace nested data structures in logs, and analyze application behavior. For example, formatting a structured log entry reveals the timestamp, log level, message, and contextual data clearly.
  • Editing Configuration Files: Modern applications use JSON for config files: package.json (Node.js), composer.json (PHP), tsconfig.json (TypeScript), launch.json (VS Code), etc. When these files are minified or poorly formatted, editing them becomes error-prone. Formatting ensures proper indentation, making it easy to spot syntax errors (missing commas, unclosed brackets) and understand configuration structure. Always format before editing, and validate after.

JSON: The Universal Data Format

JSON (JavaScript Object Notation), Douglas Crockford tarafından belirtildi ve RFC 8259 (2017) ile standartlaştırıldı. JSON, JavaScript nesne sözdizimini temel alan hafif, dilden bağımsız bir veri formatıdır. Web API'ları, yapılandırma dosyaları ve veri değişimi için baskın format haline geldi ve birçok uygulamada XML'i büyük ölçüde değiştirdi.

JSON Security Considerations

JSON formatting does not validate data safety. Always validate and sanitize JSON content from untrusted sources before using it in your application. Learn about encoding security

Programlama Dillerinde JSON Biçimlendirme

Her programlama dili JSON biçimlendirebilir (güzelleştirebilir) ve küçültebilir. İşte örnekler:

// Beautify (pretty print)
$formatted = json_encode($data, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);
// Result: formatted with 4-space indent

// Minify (compact)
$minified = json_encode($data);
// Result: no whitespace

// With custom options
$json = json_encode($data,
    JSON_PRETTY_PRINT |
    JSON_UNESCAPED_UNICODE |
    JSON_UNESCAPED_SLASHES
);

// Parsing (with error handling)
$data = json_decode($jsonString, true);
if (json_last_error() !== JSON_ERROR_NONE) {
    echo "JSON Error: " . json_last_error_msg();
}

// Beautify with 2-space indent
const formatted = JSON.stringify(data, null, 2);

// Beautify with 4-space indent
const formatted = JSON.stringify(data, null, 4);

// Minify (compact)
const minified = JSON.stringify(data);

// Parse with error handling
try {
    const data = JSON.parse(jsonString);
} catch (error) {
    console.error("JSON parse error:", error.message);
}

// Replacer function (custom serialization)
const json = JSON.stringify(data, (key, value) => {
    // Exclude private fields
    if (key.startsWith('_')) return undefined;
    return value;
}, 2);

import json

# Beautify with 2-space indent
formatted = json.dumps(data, indent=2)

# Beautify with sorted keys
formatted = json.dumps(data, indent=2, sort_keys=True)

# Minify (compact)
minified = json.dumps(data, separators=(',', ':'))
# separators removes spaces after commas and colons

# Parse with error handling
try:
    data = json.loads(json_string)
except json.JSONDecodeError as e:
    print(f"JSON error: {e.msg} at line {e.lineno}")

# Pretty print to console
print(json.dumps(data, indent=2))

import (
    "encoding/json"
    "fmt"
)

// Beautify with indent
formatted, err := json.MarshalIndent(data, "", "  ")
if err != nil {
    fmt.Println("JSON marshal error:", err)
}

// Minify (compact)
minified, err := json.Marshal(data)

// Parse with error handling
var data MyStruct
err := json.Unmarshal([]byte(jsonString), &data)
if err != nil {
    fmt.Println("JSON unmarshal error:", err)
}

// Custom indentation
formatted, _ := json.MarshalIndent(data, ">", "----")
// Prefix: >, indent: ----

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.google.gson.JsonSyntaxException;

// Beautify
Gson gson = new GsonBuilder()
    .setPrettyPrinting()
    .create();
String formatted = gson.toJson(data);

// Minify
Gson gson = new Gson();
String minified = gson.toJson(data);

// Parse with error handling
try {
    MyObject obj = gson.fromJson(jsonString, MyObject.class);
} catch (JsonSyntaxException e) {
    System.err.println("JSON error: " + e.getMessage());
}

require 'json'

# Beautify
formatted = JSON.pretty_generate(data)
# Default: 2-space indent

# Beautify with custom indent
formatted = JSON.pretty_generate(data, indent: '    ')
# 4-space indent

# Minify
minified = JSON.generate(data)

# Parse with error handling
begin
  data = JSON.parse(json_string)
rescue JSON::ParserError => e
  puts "JSON error: #{e.message}"
end

using Newtonsoft.Json;

// Beautify (pretty print)
string formatted = JsonConvert.SerializeObject(data,
    Formatting.Indented);

// Minify (compact)
string minified = JsonConvert.SerializeObject(data,
    Formatting.None);

// Parse with error handling
try
{
    var obj = JsonConvert.DeserializeObject<MyObject>(jsonString);
}
catch (JsonException ex)
{
    Console.WriteLine($"JSON error: {ex.Message}");
}
