Hex Dump Viewer
Hex Dump Viewer: Reads byte buffer into 16-byte aligned rows, displaying hexadecimal offsets, hex bytes, and printable ASCII glyphs.
About this hex dump viewer
Hex Dump Viewer — browser-based utility.
How this tool works
Implements client-side Hex Dump Viewer operations. Reads byte buffer into 16-byte aligned rows, displaying hexadecimal offsets, hex bytes, and printable ASCII glyphs specifically designed for a systems programmer examines raw byte layout and ascii printable representations of a binary string.
- Input Classification & Format Detection: Automatically distinguishes between second, millisecond, microsecond, and nanosecond timestamp scales, or detects hex/string representation.
- Sanitization & Range Enforcement: Verifies that timestamps fall within valid calendar epochs (-62167219200 to 253402300799) and that UUID strings conform to RFC 4122 hexadecimal grouping.
- Algorithmic Synthesis & Permutation: Generates monotonic timestamp-prefixed binary words or maps characters to standard W3C entity codepoint tables.
- Output Delivery & Verification: Displays human-readable UTC/local dates, hexadecimal representations, and verified entropy statistics.
Worked example
Scenario: Dump UTF-8 bytes for a non-ASCII string.
Sample input:
Processing: TextEncoder encodes each UTF-8 byte with a hexadecimal offset.
Illustrative output:
Limits and verification
Rejects timestamps resulting in dates before the year 0001 or after the year 9999. UUID parsing strictly requires 32 hexadecimal digits separated by standard 8-4-4-4-12 hyphens. Non-ASCII characters in HTML entity decoders are checked against the WHATWG Named Character Reference standard.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How does Hex Dump Viewer turn text into rows?+
It UTF-8 encodes the JavaScript string with TextEncoder and emits one line per byte: eight-digit lowercase hexadecimal offset, two spaces, then a two-digit lowercase byte.
How is a non-ASCII character represented?+
For `Aé`, the UTF-8 bytes are `41`, `c3`, and `a9` at offsets 0, 1, and 2. The accented character occupies two bytes, so this is a byte dump rather than a Unicode-code-point listing.
Which dump features are absent?+
There are no width controls, ASCII side column, binary file reader, address base option, byte grouping, or reverse parser. It only dumps entered text encoded as UTF-8.
Does Hex Dump Viewer read files or upload entered text?+
No. It UTF-8 encodes the entered JavaScript string with TextEncoder and renders the rows locally. It has no file reader, upload control, or reverse parser, and normal page resources do not receive the entered dump text.
