Parser & Formatter

WHAT IT DOES

Parser & Formatter is a developer tool that converts data between different representations: JSON, hex, Base64, and plain strings. Select the input format and output format, enter your data, and the tool parses the input according to the selected format and converts it to the target format. It displays the conversion status, input format, output format, and the converted result in a clean preview. This is essential for developers working with data in different encodings, debugging API responses, preparing data for smart contracts, or converting between common data representations.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Select the input format — JSON, Hex, Base64, or Plain string. Select the output format — the same options. Enter the data you want to convert in the text area. Click "Parse & format" to perform the conversion. The tool displays the conversion status, input format, output format, and the converted result. For example, enter a JSON object and convert it to hex, or enter a Base64 string and convert it to JSON. The tool handles common data types and provides a preview of the converted data. This is useful for preparing data for blockchain transactions, debugging, or working with APIs.

TECHNICAL MECHANISM

The tool uses JavaScript's built-in parsing and encoding functions. For JSON input, it uses JSON.parse() to parse the data, and JSON.stringify() to format it. For hex input, it converts the hex string to bytes using Uint8Array and then decodes it with TextDecoder. For Base64 input, it uses atob() to decode and btoa() to encode. For plain string input, it treats the data as a raw string. The conversion process first parses the input according to the selected input format, then formats the parsed data according to the output format. The tool handles errors gracefully — if parsing fails, it displays an error message. The converted result is displayed in a monospace preview with a format badge. All operations are performed client-side — no data is stored or transmitted. The tool is read-only and does not sign any transactions.

WHAT IT CANNOT SEE

The tool cannot parse or format data that requires external context or dependencies — it only works with the provided data. It cannot handle extremely large datasets without performance degradation — very large inputs may cause slowdowns. It cannot validate the semantic correctness of parsed data — the tool only checks syntax. It cannot automatically detect the input format or encoding without user specification — the user must select the format. It cannot parse binary or non-text data formats — only text-based formats are supported. It cannot convert between formats that require additional context (e.g., date formats, custom encodings). The tool is read-only and does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains for the wallet connection, but the parser and formatter are chain-agnostic. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported for wallet connection but the conversion works regardless. The tool assumes UTF-8 encoding for text data. Hex strings should not include the 0x prefix (the tool handles it if present). Base64 strings should be properly padded. The tool does not store any data — all operations are performed client-side. The tool is provided as-is with no warranty or liability. Always verify the converted data before using it in production.
