csvjson is a free, browser-based toolkit for converting data between the formats developers and analysts use daily: JSON, CSV, Excel, YAML, XML, SQL, and more. Every conversion runs entirely in your browser. Nothing is uploaded to a server. Nothing is logged. No account required, no file size limits. Converters include: JSON โ CSV, Excel, YAML, XML, SQL, TSV CSV โ JSON, Excel, SQL Excel โ JSON, CSV XML โ JSON, YAML โ JSON, NDJSON โ JSON Developer tools include: JSON Formatter, Validator, Schema Validator JSON Path Finder, Flatten JSON JWT Decoder, Regex Tester, Diff Checker SQL Formatter, Cron Builder Base64, URL Encode/Decode, Hash Generator (SHA-256/512) UUID Generator, Timestamp Converter CSV Viewer/Editor, CSV Cleaner QR Code Generator, Markdown Preview Developers use it to transform API responses, generate SQL seed data, decode JWTs, and validate schemas. Analysts use it to clean and reformat exports before loading into Excel or Sheets. Non-technical users use it to open a JSON file or convert a CSV without writing any code. Most online converters upload your data to their servers. csvjson processes everything locally using JavaScript โ your data never leaves your device. This matters for anyone handling production data, customer records, or anything governed by data privacy policies
The ultimate JSON editing experience with tools for filtering, sorting, comparison, conversion all at one place. Built for developers who demand productivity and elegance.

TrueJsonTrueJson's answer:
Every developer knows the painโjumping between a dozen scattered JSON tools just to get one job done. One site to format, another to validate, a third to convert, each with clunky, outdated interfaces and inconsistent behavior. What should be a simple taskโediting, validating, or comparing JSONโturns into a frustrating scavenger hunt across the web. Add in the constant risk of syntax errors, broken structures, and lost time, and JSON becomes less of a universal data format and more of a daily obstacle.
Thatโs where True JSON comes inโthe all-in-one studio built for clarity, speed, and collaboration. You can edit, validate, prettify, minify, sort, and filter your data with precision. Generate or validate schemas, convert between JSON, XML, CSV, and YAML, perform diff checks, save files securely, collaborate through comments and shared access, and automate everything via API integration. Every tool you need, unified in one sleek, intelligent workspace.
TrueJson's answer:
It treats JSON as a workflow, not a one-off task. It brings editing, validation, prettify/minify, sorting and filtering, schema generation and validation, format conversions (JSON โ XML/CSV/YAML), diffing, file saving, collaboration with comments, and API-based automation into a single, consistent workspace. The value isnโt any single featureโitโs the fact that everything works together in one place, with a modern interface and predictable behavior.
TrueJson's answer:
This phase is intentional. Weโre focused on validating the core workflow, refining usability, and making sure the product genuinely solves the fragmentation problem before scaling into enterprise adoption. Several teams are actively using it in day-to-day development and review workflows, and those early users are shaping what TrueJson becomes next.
We expect larger customers to follow as the product matures, but for now, the priority is building something solid, useful, and trustedโrather than chasing logos too early.
TrueJson's answer:
The primary audience of TrueJson is people who work with JSON frequently and operationally, not occasionally.
At the core, this includes software engineers, backend and frontend developers, and API-focused teams who deal with JSON as part of their daily workflowโconfig files, API payloads, responses, schemas, and integrations. For them, JSON is not just a data format but a critical dependency, and small inefficiencies or errors can quickly cascade into bugs, broken deployments, or wasted time.
Beyond individual developers, TrueJson also serves teams and technical leadsโsuch as senior engineers, tech leads, and CTOsโwho care about consistency, reliability, and collaboration. Features like schema validation, diffing, saved files, comments, and API integration make it relevant for code reviews, CI/CD pipelines, and shared standards across teams.
Finally, TrueJson is accessible to learners and non-specialist technical roles (QA engineers, product engineers, data analysts) who work with JSON but may not want to assemble and maintain a fragmented toolchain. Its value lies in reducing friction for anyone who needs JSON to be correct, readable, and trustworthyโregardless of whether theyโre writing code all day or supporting systems around it.
TrueJson's answer:
The story behind TrueJson began with a simple but persistent frustration: JSON is everywhere, yet working with it has always been fragmented. Formatting in one tool, validation in another, conversions and diffing somewhere elseโeach task breaking flow and adding invisible overhead that developers quietly accept as โnormal.โ
TrueJson was created to challenge that assumption. Instead of another single-purpose utility, it set out to give JSON a proper homeโa unified, modern workspace where all common JSON tasks live together. The idea was straightforward: reduce friction, remove context-switching, and make working with JSON feel clear, reliable, and complete again.
