What these tools cover

CodeAva tools are browser-based utilities built for the kinds of tasks that come up constantly during development: formatting a JSON response, decoding a JWT to inspect claims, comparing two text blocks, testing a regex pattern, or checking what headers a server is actually returning. Each tool is focused on one job and designed to give you a usable output immediately.

They are useful for developers reaching for a quick formatter or validator mid-session, QA engineers comparing payloads and testing input patterns, founders and technical site owners checking what their server is returning, and agencies reviewing client sites before or after launch.

Most tools process input locally in your browser using native browser APIs — nothing is sent to a server. A small number of tools, like the HTTP Headers Checker, make a server-side fetch to inspect the URL you provide. Each tool page notes what it does and does not transmit. No account or signup is required.

What you can do with CodeAva tools

Validate JSON before sending API payloadscatch syntax errors and structural issues before a request fails.
Convert JSON and YAML configs safelyswitch between API payloads and human-edited config formats without hand-fixing braces or indentation.
Clean spreadsheet and SaaS exports locallyconvert CSV customer lists or operational exports into JSON, or flatten JSON into CSV for spreadsheet workflows.
Decode JWT claims for faster auth debugginginspect token contents without needing the signing secret.
Compare text or code changes before publishingsee exactly what changed between two versions, line by line.
Format code snippets for reviews and documentationconsistent indentation for cleaner PRs, docs, and tutorials.
Inspect HTTP response headers after deploymentverify security headers, caching rules, and redirects are correct.
Generate hashes for integrity checksproduce SHA-256 or SHA-512 fingerprints to compare or verify values.
Parse cron schedules and preview next run timestranslate cron to plain language, validate the right dialect, and compare server timezone with local time.
Generate strong passwords or passphrases locallycreate random credentials in the browser with secure randomness and practical strength guidance.
Encode and decode Base64 strings quicklyuseful for working with credentials, tokens, and binary data in transit.
Create QR codes for URLs and campaign assetsgenerate scannable codes for print, signage, or link sharing.
Convert Unix timestamps while debugging logs or APIsauto-detect seconds vs milliseconds and switch between UTC and local time.
Generate unique IDs for databases, APIs, and distributed systemscreate UUID v4, UUID v7, ULID, or Nano ID values in bulk with one click.
Inspect mystery identifiers from logs, payloads, or CSV exportsvalidate UUIDs and ULIDs, detect versions, and decode timestamps from sortable IDs.
Compress and convert images for web performancereduce file size, convert to WebP or AVIF, resize for social or OG images, and fix Lighthouse next-gen format warnings — all locally in the browser.
Inspect and strip hidden metadata from imagesdetect GPS coordinates, device details, and author info embedded in photos, then export a clean copy without uploading the file anywhere.
Convert text to the right case format or clean messy pasted contenttransform titles, headings, and variables to Title Case, camelCase, snake_case, or any other format, and remove duplicates, blank lines, and stray HTML in one step.
Parse, decode, or rebuild a URL with query parametersbreak long or encoded URLs into clean components, edit query parameters live, detect UTM tags, and copy the rebuilt link without sending it to any server.
Inspect a QR code safely before opening the linkdecode QR code images, screenshots, or webcam frames locally, review URL risk signals, and extract Wi-Fi credentials or contact cards without scanning on a phone.
