Review first

Before you choose a developer tools page

Use these category-specific checks to pick the right tool, protect sensitive input, and avoid relying on output before the destination workflow confirms it.

  • Remove secrets before pastingUse representative snippets without tokens, private keys, customer records, unreleased credentials, or production-only values.
  • Preserve enough contextKeep headers, nesting, delimiters, repeated keys, encodings, or surrounding lines when they affect parsing or validation.
  • Validate in the final systemTreat output as a fast browser check, then confirm with your schema, compiler, runtime, API client, database, or test suite.

Use results well

After you choose from Developer Tools

These shared handoff checks help results stay reviewable after you copy, download, publish, import, or continue into another ClearUtils page.

  • Validate in your stackRun formatted, converted, decoded, or extracted output through the parser, schema, tests, runtime, or API client that will consume it.
  • Keep redacted contextAttach a safe sample, input shape, delimiter, encoding, timestamp zone, or source-snippet note so the transformation remains reproducible.
  • Chain compatible utilitiesMove between formatters, validators, encoders, parsers, and extractors only when the output type matches the next tool input.
Tool groups

Find the right developer tools group

Use this map to jump between stronger developer-data clusters such as formatters, validators, encoders, converters, source extractors, and API debugging helpers.

What you can do with these tools

Debug JSON and API payloads

Validate syntax, check common JSON Schema rules, format JSON Lines / NDJSON records, validate or format YAML and TOML, convert JSON config snippets to TOML or TOML back to JSON, decode, and inspect small snippets copied from APIs, logs, query strings, URLs, Unix timestamps, ISO date checks, timestamp-to-date checks, time zone notes, XML payloads, image data URIs, or config files.

Parse query and URL data

Use UTM Builder for new campaign links, URL Parser for full links, Query String Parser to parse query string values, and URL Encoder/Decoder when copied parameters are percent-encoded.

Format or reshape structured snippets

Move between JSON Formatter, JSON Lines Formatter, YAML Validator, YAML Formatter, TOML Formatter, JSON to TOML, TOML to JSON, XML Validator, XML Formatter, XML Minifier, HTML heading/paragraph/list/comment/media/source, inline-style, link-relation, and meta-refresh extractors, CSV Formatter, CSV Column Extractor, CSV to List, List to CSV, and Delimiter Converter depending on whether the source is JSON, JSON Lines, YAML, TOML, XML, HTML, tabular data, or plain lines.
