Format, validate, and optimize JSON structures
Format, validate, minify, and convert JSON for API debugging, config review, and typed frontend work. Start by formatting unreadable payloads, validate syntax before shipping, then minify or generate TypeScript when the workflow needs it.
Priority tools
Start with the most common workflows in this category, then move to adjacent tools when needed.
JSON Formatter
Format JSON with readable indentation for debugging and documentation.
JSON Validator
Validate JSON syntax in the browser and find errors before using payloads in APIs.
JSON Log Parser
Extract, unescape, and format JSON trapped inside CloudWatch, Lambda, Docker, and API log strings.
JSON Minifier
Minify valid JSON into a compact single line without changing objects, arrays, or values.
CSV to JSON
Convert CSV content or files into JSON using browser-based processing.
XLSX to JSON
Convert the first worksheet of an XLSX file into JSON in the browser.
Recommended workflows
Contextual links for combining tools without leaving the cluster.
Debug an API payload
Extract JSON from logs when needed, format unreadable payloads, validate syntax, then minify the final copy.
Generate frontend types
Validate and format a representative JSON sample before generating TypeScript interfaces from the response shape.
Convert source data to JSON
Turn CSV, XLSX, or HTML input into JSON before formatting, validating, or sending it into another developer workflow.
