Articles in JSON & Data category

Understand how structural JSON diff tools work: recursive object comparison, JSON Pointer paths, ordered and keyed array matching, LCS trade-offs, JSON Patch application, complexity limits, redaction, and API/configuration use cases. Includes a bounded JavaScript implementation.

Learn when to pretty-print, minify, compress, or canonicalize JSON. Separate whitespace changes from gzip/Brotli transport compression, preserve numeric and Unicode semantics, avoid accidental key-order or secret leaks, and build reproducible validation workflows.

A practical guide to JSON Schema validation with the 2020-12 dialect. Learn assertions, annotations, references, formats, conditionals, unevaluated properties, error handling, API contracts, version evolution, resource limits, and the security boundaries Schema validation does not provide.

A context-aware comparison of JSON and XML. Examine data models, namespaces, mixed content, schemas, streaming and DOM parsing, media types, ecosystem contracts, security configuration, migration loss, and performance measurement before choosing a format.

Learn how to compare JSON by structure rather than formatting. Define object and array semantics, distinguish null from missing fields, produce JSON Pointer paths, handle numbers and duplicate keys, and choose local or hosted workflows with explicit privacy and resource limits.

Choose and verify PDF conversion workflows for rendering, compression, merging, splitting, and image import. Covers fidelity, metadata, encryption, signatures, privacy, accessibility, and reproducible output checks.

Learn the JSON string grammar, required escapes, Unicode and surrogate pairs, nested JSON, and safe serialization in JavaScript, Python, Go, and Java. Distinguish JSON escaping from URL encoding, Base64, HTML escaping, SQL parameters, and security validation.

Convert Unix timestamps without confusing units, resolution, and clock accuracy. This guide covers explicit seconds/milliseconds/microseconds/nanoseconds contracts, integer arithmetic, negative epochs, JavaScript precision, monotonic clocks, time zones, leap seconds, database storage, JSON serialization, and overflow-safe code.

A loss-aware guide to converting JSON and CSV. Define row and column schemas, flatten nested objects, choose array and null policies, preserve quoting and newlines, control type inference and encoding, prevent spreadsheet formula injection, and validate round trips with JavaScript, Python, and Go.

Learn JSONPath with the RFC 9535 data model and query concepts. Compare child, wildcard, descendant, index, slice, and filter selectors; distinguish standard syntax from library extensions; and design bounded, read-only queries with JavaScript, Python, and Java examples.

A technical deep-dive into YAML and JSON covering YAML's implicit type coercion traps (the Norway problem, boolean hell), deserialization security vulnerabilities (YAML bombs, arbitrary code execution via tags), YAML 1.1 vs 1.2 specification differences, what is lost in each conversion direction, parsing library security postures (PyYAML vs ruamel.yaml vs strictyaml), and when TOML is the better alternative to both.

Master TOON (Token-Oriented Object Notation) format to dramatically reduce LLM API costs. Learn how TOON saves 30-50% tokens compared to JSON, with practical examples for ChatGPT, Claude, and other AI models.

Master Unix timestamp conversion techniques. Learn seconds/milliseconds/nanoseconds conversion, timestamp to date online. Free online converter tool with JavaScript/Python code examples!

Learn how to design reliable document workflows covering PDF manipulation, format conversion, batch processing, access control, audit trails, and API integration. The guide focuses on measurable throughput, failure handling, data protection, and maintainable automation rather than one-size-fits-all productivity promises.

Master timestamp conversion techniques. Learn UTC storage, timezone conversion, ISO 8601 format, DST handling. Complete JavaScript/Python/Java/SQL code examples included!
