Modules 1

JSON Foundations

Understand the structure, vocabulary, and rules behind valid JSON.

  1. 1What JSON Is and Where It AppearsJSON is a text format for structured data. You see it in APIs, config files, app settings, and exports.json-formatterjson-viewer7m
  2. 2JSON Syntax RulesValid JSON follows strict punctuation rules. Small quote, comma, or bracket mistakes can break the whole payload.json-formatterjson-path-tester7m

Modules 2

Format, Validate, and Debug

Turn messy payloads into readable JSON and learn a repeatable debugging workflow.

  1. 3Format JSON for ReadabilityFormatting does not change the data. It adds indentation so humans can scan nested objects and arrays.json-formatterjson-viewer7m
  2. 4Compare JSON VersionsJSON diffing helps you spot changed fields, missing values, and API response regressions.json-diffjson-viewer8m

Modules 3

JSON Conversion Workflows

Convert JSON to spreadsheet-friendly and config-friendly formats without losing structure.

  1. 5Convert JSON to CSVCSV works well for flat tables. JSON works better for nested data. Learn when conversion is safe.json-to-csvcsv-to-json8m
  2. 6JSON vs YAML vs XMLChoose the format based on the job: APIs, configs, documents, or human editing.json-to-yamlyaml-to-jsonjson-to-xml8m
