How to use Extract Unicode Range
- 1. Paste the text to filter. Drop the mixed text into the input pane. It can be a sentence, a scraped page or a log line containing letters, symbols and emoji from several different scripts at once.
- 2. Set the code point interval. Enter the From code point (hex) and To code point (hex) bounds. For example 0041 to 005A keeps only uppercase Latin letters; 1F600 to 1F64F keeps only smiley emoji.
- 3. Read the filtered result. Every character outside the interval is dropped and the rest are kept in their original order, so the output is a direct subsequence of the input restricted to the range you gave.
- 4. Copy what you kept. Copy the filtered text out of the output pane for use in another tool, a report or a script. Adjust the bounds and rerun if you need a different slice.
When to use Extract Unicode Range
Extract Unicode Range pulls out only the characters whose code points fall inside a hex interval you choose. It is for isolating one script, block or emoji group from text that mixes several, without writing a regular expression by hand.
- Isolating uppercase letters from a mixed string. A scraped username field contains random casing and punctuation. Setting the range to the uppercase Latin block pulls out just the capital letters, useful for building an initials or acronym.
- Pulling emoji out of a chat export. A Discord message log has text and emoji interleaved. Setting the range to the emoji block extracts just the symbols so you can count which reactions appeared most often.
- Checking which CJK characters appear in a dataset. A CSV column mixes English labels with Chinese characters. Restricting the range to the CJK Unified Ideographs block confirms which rows actually contain Chinese text.
- Stripping everything but digits from OCR output. Scanned receipt text has noisy symbols around the numbers. Narrowing the range to 0030 to 0039 keeps only the digit characters so you can parse the amount separately.

About the Extract Unicode Range tool
Extract Unicode Range runs as plain JavaScript in your browser tab, with no server behind it. Quickly filter Unicode symbols that are within the given code point interval. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Unicode Tools section, 98 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including From code point (hex) and To code point (hex), and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Extract Unicode Range cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
