Text and Data Tools for JSON, CSV, XML, and Markdown
Use this category to format JSON, convert CSV and XML, transform YAML and TOML, compare text diffs, test regex patterns, and handle Markdown and HTML conversions quickly.
Because processing happens in your browser, copied payloads, logs, config snippets, and draft content stay local while you clean, validate, and transform data.

Frequently Asked Questions
- Are pasted payloads or logs sent anywhere?
- No. Text and data transformations run client-side, so API payloads, internal logs, and configuration snippets are processed locally in your browser.
- Can I chain multiple text tools in one workflow?
- Yes. A common flow is CSV to JSON conversion, then JSON formatting, then regex cleanup before exporting the final data block.
- Do format conversions preserve key ordering and structure?
- Most tools preserve logical structure, but exact formatting and ordering can vary by format rules. Review final output before committing to production systems.
- What is the best starting tool for debugging malformed payloads?
- Start with JSON Formatter for strict validation. If the source is not JSON, use YAML/JSON/TOML or XML to JSON first, then reformat and validate the result.
