Converter tools for data and units
Move between formats and measurement systems with utilities that show their assumptions — ideal for spreadsheets, APIs, localization, and quick math without spreadsheet bloat.
Structured data conversions
APIs export JSON; analysts want CSV. The JSON to CSV and CSV to JSON tools flatten and rebuild tabular data with options for headers and nesting behavior. For XML-heavy legacy systems, try XML to JSON.
Documentation workflows benefit from Markdown to HTML and HTML to Markdown when migrating CMS content or README files.
Units, numbers, and file sizes
The Unit Converter covers length, mass, temperature, and more with explicit unit definitions. Developers switching between hex, binary, and decimal will use the Number Base Converter; storage estimates use the File Size Converter with binary (KiB) vs decimal (KB) clarity.
Historical or puzzle contexts may need the Roman Numeral Converter — a niche but handy teaching aid.
Time, color, and currency
Remote teams schedule across zones with the Time Zone Converter. Design handoffs use the Color Format Converter between HEX, RGB, and HSL.
The Currency Converter fetches reference rates from a public API — treat figures as estimates, not financial advice or locked trading prices.
Frequently Asked Questions
Why does JSON to CSV look different from Excel?
Nested objects flatten differently depending on options. Always spot-check wide exports before importing to production databases.
Are currency rates live?
Rates come from third-party APIs and may lag market prices. Verify with official sources for transactions.
Do converters upload my data?
Most converters process pasted input locally. Network-backed tools note their API calls on the tool page.
