JSON Tools Collection
Complete suite of JSON utilities for developers. Format, validate, convert, compare, and visualize JSON data with our specialized tools.
Format & Validate
Ensure your JSON is clean, correct, and readable
JSON Formatter
Paste a minified JSON blob or raw API response and instantly expand it into clean, indented, syntax-highlighted output. Ideal for debugging REST payloads, reading compact config files, or making log dumps human-readable before sharing with your team.
Use tool →JSON Validator
Drop your JSON into the validator to catch missing commas, trailing commas, unquoted keys, and bracket mismatches before they hit production. Get line-level error messages that tell you exactly what broke and where, saving you from staring at a stack trace.
Use tool →JSON Analyzer
Feed in a large JSON dataset to get an instant structural summary: nesting depth, key frequency, array sizes, null counts, and type distribution per field. Use it before writing parsing code to understand the shape of an unfamiliar API response or data export.
Use tool →JSON Schema Generator
Paste a sample JSON payload and generate a compliant JSON Schema draft with inferred types, required fields, and array item definitions. Useful when you need to document an API contract, set up validation rules, or generate TypeScript interfaces from real data.
Use tool →View & Explore
Navigate and inspect JSON structures visually
JSON Viewer
Load a JSON file or paste raw data to browse it as a collapsible tree. Click any node to drill into nested objects, copy paths as dot-notation strings, or search keys across the entire document. A faster alternative to scrolling through raw text in your editor.
Use tool →JSON Compare
Paste two JSON documents side by side and see every difference highlighted: added keys, removed values, changed types, and reordered arrays. Essential for reviewing API version upgrades, checking config drift between environments, or verifying data migration scripts.
Use tool →JSONPath Query
Write a JSONPath expression to extract specific nodes from a large document without writing code. Supports filters, wildcards, and recursive descent. Perfect for pulling all user emails from a nested API response or checking if any item in an array matches a condition.
Use tool →JSON Extractor
Paste a messy log line, HTML snippet, or mixed-format string that contains embedded JSON and the extractor pulls out every valid JSON object it finds. Handy when you need to rescue JSON trapped inside application logs, curl output, or copy-pasted browser console results.
Use tool →Convert JSON To
Transform JSON into formats your tools and teammates expect
JSON to CSV
Drop a JSON array of objects and get a CSV file with auto-detected columns. Nested fields are flattened into dot-separated headers so you can open API exports directly in Excel or Google Sheets without manual wrangling. Handles arrays of uneven objects gracefully.
Use tool →JSON to XML
Convert any JSON structure to well-formed XML with configurable root element naming and attribute-vs-element mapping. A lifesaver when you need to feed modern JSON data into legacy SOAP services, SAML pipelines, or enterprise middleware that still speaks XML.
Use tool →JSON to YAML
Paste a JSON config file and get clean, indented YAML output ready for Kubernetes manifests, Docker Compose files, or CI/CD pipelines. Preserves comments if present and lets you switch between block and flow styles for arrays. No more manual rewriting of cloud configs.
Use tool →JSON to SQL
Feed in a JSON array and generate CREATE TABLE statements with inferred column types, followed by INSERT rows for every object. Batch-import API data into PostgreSQL, MySQL, or SQLite in seconds without writing a single line of ETL code.
Use tool →JSON to Table
Render any JSON array as a sortable, filterable HTML table with column resizing and export options. Perfect for quickly presenting API results to non-technical stakeholders, embedding live data in documentation, or previewing a dataset before writing analysis code.
Use tool →JSON to TypeScript
Paste a sample JSON response to generate precise TypeScript interfaces with optional properties, union types for varied fields, and array element typing. Keeps your frontend types in lockstep with your backend's actual output without manual transcribing.
Use tool →Convert to JSON
Bring external data formats into the JSON ecosystem
CSV to JSON
Upload a CSV or paste tabular data and get back a clean JSON array of objects. Choose between row-per-object and column-per-key output modes, with automatic type detection for numbers and booleans. Ideal for prepping spreadsheet data for API ingestion or NoSQL imports.
Use tool →XML to JSON
Convert XML documents, SOAP responses, or RSS feeds into clean JSON with intelligent attribute-to-property mapping. Handles namespaces, mixed content, and deeply nested structures. The quickest way to modernize legacy XML data for use in JavaScript or Python services.
Use tool →YAML to JSON
Paste a YAML file from a Helm chart, Ansible playbook, or OpenAPI spec to convert it into standard JSON. Preserves all data types including timestamps and multi-line strings. Useful when your toolchain only accepts JSON but your team maintains config in YAML.
Use tool →Clean & Transform
Repair, sort, and escape JSON data
JSON Cleaner
Paste broken JSON with single quotes, trailing commas, missing brackets, or JavaScript-style comments and get back strict, spec-compliant JSON. A must-have when you copy data from browser console output, JavaScript source files, or hand-edited configuration.
Use tool →JSON Escape / Unescape
Escape special characters, newlines, and quotes in a string so it can be safely embedded as a JSON value. The reverse mode unescapes to show you the original text. Essential when building JSON strings programmatically or debugging serialization edge cases.
Use tool →JSON Sort Keys
Alphabetically sort all keys in a JSON object recursively, with optional depth limits and case-insensitive mode. Makes diffing two JSON files reliable by eliminating key-order noise, and produces consistent output for checksum-based change detection and git-friendly configs.
Use tool →Encode & Hash
Encode text, generate hashes, and handle URL-safe strings
Base64 Encoder / Decoder
Encode any text or file content to Base64 for embedding binary data in JSON, data URIs, or JWT payloads. The decoder reverses it instantly. Supports standard, URL-safe, and MIME variants. An everyday tool for API authentication headers and inline image embedding.
Use tool →HTML Entity Encoder / Decoder
Convert special characters like <, >, and & into their HTML entity equivalents for safe embedding in web pages, or decode entities back to raw text. Prevents XSS injection when rendering user-submitted content inside a JSON-driven UI.
URL Encoder / Decoder
Percent-encode query parameters, path segments, and fragment identifiers for safe URL construction. Decode garbled URLs back to readable text. Use it when building REST API query strings dynamically or debugging why a URL with special characters is returning 400.
Use tool →Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 checksums for any input string. Use it to verify file integrity after download, create cache-busting keys for static assets, or generate deterministic IDs from content. Copy the hex digest with one click.
Use tool →Data Utilities
Everyday helpers for spreadsheets, timestamps, and number bases
CSV to Excel
Upload a CSV file and download it as a properly formatted .xlsx workbook with auto-sized columns and frozen headers. No need to open Excel and import manually. Ideal when a colleague asks you to "just send it as an Excel file" and you only have raw CSV exports.
Use tool →Remove Duplicate Rows
Upload a CSV or Excel file, pick the columns that define uniqueness, and get back a deduplicated dataset with a summary of removed rows. Works on multi-column keys and case-insensitive matching. Clean up mailing lists, user exports, and merged datasets in one step.
Use tool →Merge CSV Files
Combine multiple CSV files with identical or overlapping column structures into a single unified dataset. Choose between row-stacking append and key-based join modes. Perfect for consolidating monthly reports, combining data exports from different sources, or merging split logs.
Use tool →Batch File Renamer
Rename dozens of files at once using find-and-replace patterns, sequential numbering, case conversion, and extension changes. Preview the result before applying. Use it to normalize photo exports, clean up downloaded report filenames, or standardize asset naming conventions.
Use tool →Unix Timestamp Converter
Convert Unix epoch timestamps to human-readable dates and vice versa, with timezone support and ISO 8601 formatting. Paste a timestamp from an API response, database query, or log file to see the actual date and time without mental math or Python one-liners.
Use tool →Number Base Converter
Convert integers between binary, octal, decimal, and hexadecimal representations in real time. Handy when reading memory dumps, decoding color values, interpreting permission bitmasks, or working with hardware register addresses that switch between bases.
Use tool →Developer Tools
Utilities every developer needs in their daily workflow
CSS & JS Minifier
Paste raw CSS or JavaScript and get a minified version with whitespace stripped, comments removed, and identifiers shortened where safe. Drop the output directly into your production build pipeline or use it to shrink inline styles before embedding in HTML.
Use tool →JWT Decoder
Paste a JSON Web Token to decode its header and payload into readable JSON without needing a library or CLI tool. Shows claims, expiration time, issuer, and custom fields. Does not verify signatures—use it for quick inspection during API debugging and auth flow testing.
Use tool →PDF Splitter
Upload a multi-page PDF and extract specific page ranges into separate files. Extract just the invoice page from a statement, split a merged report into per-chapter PDFs, or pull out the signature page for standalone filing. No Acrobat license required.
Use tool →Regex Tester
Write and test regular expressions against sample text with real-time match highlighting, capture group extraction, and substitution preview. Supports JavaScript and PCRE flavors. Use it to craft a validation pattern for JSON string fields or extract structured data from logs.
Use tool →UUID Generator
Generate RFC-compliant UUIDs in v1 (time-based), v4 (random), and v5 (namespace) formats with a single click. Copy a batch of 10 or generate one at a time. Use v4 for database primary keys and API resource IDs; use v5 when you need deterministic IDs from input strings.
