Converters
One format goes in, a different one comes out — data formats, encodings, cases, numbers and units, converted instantly and entirely in your browser.
Data rarely arrives in the shape you need. An API returns JSON when your spreadsheet wants CSV; a string needs Base64 encoding; a measurement is in the wrong unit.
This category is the drawer of "turn this into that" tools — data formats, text encodings, number bases, and real-world units.
Each conversion is instant and runs on your device.

Moving between data formats
Structured data is only useful in the right container. The JSON to CSV Converter flattens an API response into a spreadsheet, and the CSV to JSON Converter does the reverse for feeding data back into code.
Working across a stack, the JSON to YAML Converter and JSON to TypeScript tools translate the same data into config and type definitions.
Encoding and decoding
Encodings show up everywhere from data URLs to auth tokens. The Base64 Encode and Decode tool handles the most common case, with Base32 and Base58 variants for niche needs.
Text, numbers, and units
Smaller conversions still save time. The Case Converter switches text between camelCase, snake_case, and title case, while the number base and unit converters handle binary-to-decimal and metric-to-imperial in one step.
Everything converts locally — your data is never sent to a server.

Frequently Asked Questions
Do these converters upload my data?
No. Every converter runs in your browser, so the data you paste or upload stays on your device.
Can I convert JSON to a spreadsheet format?
Yes. The JSON to CSV Converter flattens JSON into CSV rows you can open in Excel or Google Sheets, and the reverse converter turns CSV back into JSON.
What is the difference between Base64, Base32, and Base58?
They are different encoding alphabets. Base64 is the most common for data URLs and tokens; Base32 is case-insensitive and used in some OTP systems; Base58 avoids ambiguous characters and is common in crypto addresses.
Are the conversions lossless?
For data-format and encoding conversions, yes — the information is preserved exactly. Unit conversions are rounded to a sensible precision you can usually adjust.
