ASCII Table: Search and Copy Character Codes Online
Look up any of the 128 US-ASCII characters and its decimal, hexadecimal, octal, or binary code. Search by character name or by a value such as 65, 0x41, 101, 1000001, or A. When you find the value you need, click its table cell to copy it instead of retyping the code.
The ASCII Table is a quick reference for all 128 characters in US-ASCII, the 7-bit character set. Search for a character by name or enter a value such as 65, 0x41, 101, 1000001, or A. Each table entry provides the character’s code in decimal, hexadecimal, octal, and binary, and you can click a cell to copy it.
To find a value, search the table using a representation you know or browse by scrolling. The table lets you search by name and by the displayed code forms, so you can move between a character and its numeric values without calculating each base yourself. There are no conversion options to configure: the available representations are shown in the table.
ASCII assigns numeric codes to characters. Seeing the same code in decimal, hexadecimal, octal, and binary is useful when a programming language, document, or technical reference presents the value in a different base. Use the table as a lookup when you need to check a code, compare representations, or copy a character value accurately.
The ASCII Table runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server. It works offline once the page has loaded, so you can continue looking up codes without an active connection.
This reference is useful for developers, DevOps engineers, and anyone who works with text or character codes. Whether you know the character, its name, or only one form of its code, the ASCII table helps you find the other values and copy the one you need.
Step 1: Search the ASCII table or scroll through it to browse all 128 US-ASCII characters.
Step 2: Enter a character name or a value in a supported representation, such as 65, 0x41, 101, 1000001, or A.
Step 3: Check the matching character and its decimal, hexadecimal, octal, and binary codes.
Step 4: Click the table cell for the value you need to copy it.
Use case: Look up an ASCII table value without leaving your editor. Search by a character or code and copy the matching cell.
Use case: Verify the exact spelling of a character name or code you only partly remember. Searching helps you find the matching table entry.
Use case: Copy a correct value instead of retyping it from memory. The table shows the code in decimal, hexadecimal, octal, and binary.
Use case: Check a character code while debugging text or code that uses ASCII values. Comparing the character with its listed codes can help confirm the value.
Use case: Find the equivalent hexadecimal or binary value when working from a decimal ASCII code. Search using the representation you already have.
Use case: Look up a character by name when you do not know its numeric code. The table can be searched by name as well as by code.
Use case: Confirm a value before adding it to technical notes or documentation. Copy the table cell to avoid entering a different value by mistake.
