Text to ASCII

“Text to ASCII” sounds like a pipeline step, but most people are searching for a single-purpose page. They have a small piece of text and they want the numeric codes that represent it, usually to feed another tool, to write a test case, to debug hidden whitespace, or to match a specification that was written in numeric form.

This page outputs decimal ASCII values. For example, ABC becomes 65 66 67. You can choose a space delimiter or a comma delimiter depending on where you plan to paste the result. Some systems expect space-separated numbers, while others prefer comma-separated lists.

If you enable “Printable ASCII only” (the default), any character outside 32–126 is skipped and counted. That includes invisible characters like zero-width spaces and the byte order mark (BOM), which can silently break comparisons, cause surprising search results, or make a “looks identical” string fail validation. Skipping and reporting is a deliberate choice: it forces clarity about what is actually in the input.

The encoding rules here are deterministic and intentionally small. Each character is examined in order, and if it is within the selected scope it is converted to a decimal code. There is no language logic, no transformation of the text, and no “smart” normalization that might hide problems. The goal is to show you what your input is made of.

When printable-only mode is enabled, the converter includes characters in the ASCII printable band (32–126) and skips everything else. That means a normal sentence will encode cleanly, but a paragraph that includes curly quotes, em dashes, or non-breaking spaces may show skipped counts. This is useful in practice because those characters can enter text via copy/paste from word processors or messaging apps.

• Delimiter choice

  Pick space when you want compact output, or comma when you want a list format for spreadsheets, JSON snippets, or debugging logs.
• Visible vs invisible characters

  The tool calls out tabs, line breaks, non-breaking spaces, and zero-width characters so you can understand why two strings do not compare equal.
• Non-ASCII input

  If your text includes emoji or non-Latin scripts, those characters are outside ASCII. The tool reports them as skipped in printable-only mode.
• Order preserved

  Codes are generated in the same sequence as the original text. If you paste multiple lines, the output corresponds to the character order you provided.

You can paste text directly, or you can upload a file to load content into the editor. TXT and other text-like formats load as-is. PDF and DOCX extraction happens in your browser if the optional libraries are installed in your app build. When extraction succeeds, the page places the extracted text into the input box so you can encode it the same way as pasted text.

Output can be copied with one click, or exported as TXT or PDF. PDF export is useful when you need to attach a record of the encoded output (for example, in a ticket or a review). TXT export is the simplest “source of truth” format for storing the code list and reusing it later.
