Format data, encode text, generate identifiers and work with code using eleven browser-based utilities. Choose a tool below for quick development tasks without creating an account or uploading your inputs to ToolsNova.
JSON Formatter validates JSON syntax, adds readable indentation, or minifies data for compact storage. Formatting does not correct invalid structures automatically. Use JSON to CSV Converter if your input is an array of objects that you want to work with in a spreadsheet. Review the resulting column headings and values, especially with nested or uneven records.
Base64 Encoder / Decoder turns Unicode text into a portable encoded representation and reverses that process. Base64 is not encryption and cannot protect secrets. Use URL Encoder / Decoder for characters inside URL components, and HTML Encoder / Decoder when you need to escape or interpret HTML entities. These three encodings are different and should not be substituted for each other.
UUID Generator produces random UUID v4 identifiers for test data, records and prototypes. Unix Timestamp Converter converts between Unix timestamps and UTC dates, with support for seconds and milliseconds. Be careful about units: confusing them can produce an incorrect date. QR Code Generator turns a URL or text into a scannable PNG QR code; test the code with another device before publishing it.
Color Converter helps you pick colors and copy HEX or RGB values when editing styles. CSS Minifier removes comments and unnecessary whitespace from CSS; review the result before shipping because minification is not the same as full CSS optimization. SHA-256 Hash Generator calculates the digest of text for comparison and integrity-related workflows. A plain SHA-256 hash is not a suitable substitute for a password-hashing algorithm such as Argon2id.
These tools perform the listed transformations in your browser; selected text and input data are not sent to ToolsNova servers for processing. The website still delivers the code and any libraries needed to run the tools. Limits, supported inputs and outputs vary, so consult each tool's instructions.
