Text to Decimal
Convert text into decimal character codes.
Quick Tool Overview
Text to Decimal gives the character codes an ASCII or Unicode table lists — A is 65, space is 32 — and can also produce HTML numeric entities, which is how you write a character in markup when the character itself would not survive the encoding.

About the Text to Decimal
Decimal is how an ASCII table is printed and how most people first meet character codes: A is 65, a is 97, space is 32. This converter gives you those numbers for any text, which is the version that is easiest to check against a reference table.
Beyond plain codes, there is an HTML numeric entity format — A and so on — which is how you write a character in HTML when the character itself would be awkward or would not survive the encoding. That is genuinely useful for email templates, for characters that get mangled in transit, and for obfuscating an email address in page source against the simplest scrapers.
Key features of the Text to Decimal
HTML entity output
Produces A style entities ready to paste into markup or an email template.
Matches the ASCII table
Code point mode gives exactly the numbers a printed reference table lists.
Byte mode too
For when you need the UTF-8 storage values rather than the character numbers.
Column padding
Zero-pad to a fixed width so the codes align in a spreadsheet.
Full Unicode range
Emoji and CJK characters give their real six-digit code points rather than an error.

Optionally padded to a fixed width so the numbers line up in columns.
Frequently asked questions
65 for capital A and 97 for lowercase a. The difference of exactly 32 between every upper and lower case pair is not a coincidence — it is a single bit, which is what makes case conversion cheap.
A way of writing a character by its code point in HTML: A renders as A, and € renders as €. They are useful when a character might not survive the encoding of a page or an email.
Code points to match an ASCII or Unicode table, which is what most people want. Bytes when you care about how the text is actually stored, where a single character can produce up to four separate values.
Because Unicode extends well beyond ASCII's 128 characters. Emoji live above 128,000, so their code points are six digits — which is correct, and is why they are stored as four bytes.
