Hey DEV community! 👋
When debugging network streams, parsing custom file formats, or inspecting database buffers, we often extract data as raw arrays of numbers rather than human-readable text. This data typically presents itself as raw byte sequences formatted in either decimal or hexadecimal notation.
While there are online decoders available, pasting raw byte sequences into third-party sites that process data on their backend databases introduces an unnecessary data privacy risk.
To solve this, I designed a lightweight, entirely browser-based Byte to String Converter that decodes raw byte sequences locally using standard JavaScript APIs.
In this post, we will look at how bytes map to character encodings and implement a client-side JavaScript utility to decode them safely.
