About this tool
Resolve standard ASCII bytes without mixing control glyphs, HTML notation, URL component behavior, or 7-bit and 8-bit display conventions.
ASCII Table is useful when you need a fast reference for characters, control codes, and number mappings without reaching for a separate doc or script. It helps with encoding explanations, debugging, and low-level text handling where decimal, hex, and binary values matter.
- Shows decimal, hexadecimal, selectable 7- or 8-bit binary, control-picture glyphs, full control names, and common escape notation for codes 0 through 127.
- Separates HTML decimal, hexadecimal, and named references from byte percent encoding and encodeURIComponent output.
- Supports exact prefix filters such as dec:, hex:, bin:, char:, name:, escape:, html:, and url:, individual value copy, range filters, and CSV export.
How to use ASCII Table
Browse the table, locate the character or code you need, and copy the values relevant to your debugging or documentation task. If you are comparing multiple representations, keep the decimal, hex, and printable character views side by side so the mapping stays clear.

Examples you can test
Load an example, compare the result with the expected output, then replace it with your own input.
Look up a control character
Example input
Search: LF
Expected output
Decimal 10, hex 0x0A, binary 00001010
Useful when debugging line endings, logs, protocol examples, or copied text that behaves differently across systems.
Document a printable character code
Example input
Search: A
Expected output
Decimal 65, hex 0x41, binary 01000001, HTML A
Showing multiple representations side by side helps explain encodings in docs, lessons, and developer handoff notes.
Validation checklist
- Confirm whether the workflow needs standard 7-bit ASCII or an extended encoding such as Latin-1 or Windows-1252.
- Check non-printable control characters carefully because they may not show a visible glyph.
- Use the decimal, hex, and binary values consistently when copying examples into code or documentation.
- Validate URL-encoded output in the destination parser if the character will be used in query strings or forms.
