Comma Remover
Strip every comma from any text, or swap commas for spaces or newlines. Optional toggles keep commas inside numbers and quoted strings intact. Runs in your browser.
How to use the comma remover
1. Paste the text
Drop your text into the Input box. Anything from a one-line CSV row to a full essay works. The tool handles every encoding of the comma character (ASCII 0x2C is the only standard one) and ignores variants that look similar but are not commas (the Arabic comma ، or the Chinese full-width comma ，). To know what you started with, run the original through the Word Counter or Character Counter first.
2. Pick the replacement
By default, every comma is stripped. Three optional toggles change that behaviour. Replace with space turns a,b,c into a b c. Replace with newline turns the same input into one item per line, useful for converting a comma-separated list into a column. Preserve commas inside numbers keeps 1,000 intact. Preserve commas inside quoted strings keeps "Smith, John" intact when the surrounding text is a CSV row.
3. Clean and copy
Click Clean. The output appears on the right with a count of how many commas were removed. Use Copy to paste, or Download to save a .txt file.
When you need a comma remover
Commas are easy to add and surprisingly hard to remove cleanly. Five common cases where this tool helps.
1,000,000 becomes 1000000.Going the other direction?
If you have items one per line and need a single comma-separated string, use the inverse tool. Choose your separator (comma, comma+space, semicolon, custom) and paste the joined string anywhere.

The word "comma" looks like one character, but Unicode disagrees. The regular ASCII comma at U+002C is the one keyboards type in English text and the one CSV exports rely on. CSV-style data, English prose, and most programming strings all use this single codepoint. Around it sit a small family of look-alikes that the tool treats as their own glyphs: a fullwidth comma at U+FF0C common in CJK layouts, the Arabic comma at U+060C that points the opposite way, plus a few less common siblings. Each one carries grammatical or layout meaning in its own script, so collapsing them all into one bucket would corrupt mixed-language input.
The same shape carries different jobs even inside English. In 1,000,000 the commas are thousands separators (US convention); in 3,14 the same glyph is a decimal point (most of continental Europe). The Preserve commas inside numbers toggle exists for that reason, so a list export with mixed numeric formats does not silently lose digits. Oxford comma context (the optional comma before "and" in a serial list) is also worth keeping in mind: stripping it for AP-style copy means deleting a single comma per list, not every comma in the paragraph. Pair Replace with space with a follow-up "and" patch in your editor rather than running a blanket strip. To count Oxford-comma cases and splices before deciding, use the inverse-operation Comma Counter.
Comma removal patterns reference
The same Clean button covers very different jobs depending on what comes out of it. Four patterns Jose and the team reach for most often:
| Pattern | Input shape | Settings | Result |
|---|---|---|---|
| CSV row to JSON array | red, blue, green, amber | Replace with newline on; Preserve commas inside quoted strings on | Four lines ready to wrap in ["..."] brackets in a code editor |
| Pre-import database cleanup | "Lopez, Maria",Sales,$1,200 | Preserve commas inside quoted strings on; Preserve commas inside numbers on | Field-separator commas drop, internal commas in names and dollar figures stay intact |
| Prose list to bullet list | The talk covered Python, Rust, and Go. | Replace with newline on | Three short lines paste-ready into a Markdown bullet block |
| Programming string cleanup | tags=foo,bar,baz,qux | Replace with space on | Whitespace-delimited string ready for tokenizers that split on whitespace, not punctuation |
The same input plus different toggles produces wildly different output, which is the whole point: every cleanup task in the table starts from punctuation that looks identical to a human reader but means something different to the tool consuming it.

Frequently asked questions
How do I remove every comma from text?
Paste the text into the input box. Leave the Remove all commas toggle on and every other toggle off. Click Clean. Every comma is stripped and the rest of the text stays untouched.
How do I turn a comma-separated list into one item per line?
Turn on Replace with newline. Each comma becomes a line break, so a, b, c becomes three lines (a, b, c) instead of one. If your list has spaces after the comma, the leading space will land at the start of each new line. Pipe the result through /remove-whitespace/ with Trim each line on, or just turn on Trim each line in your destination editor.
Will the tool remove commas inside numbers like 1,000?
Only if you want it to. The Preserve commas inside numbers toggle skips any comma where both neighbours are digits. So 1,000 stays as 1,000 but apple, banana becomes apple banana. Turn the toggle off and 1,000 becomes 1000.
What does Preserve commas inside quoted strings do?
When this toggle is on, the tool ignores commas that fall between matched double quotes or matched single quotes. Useful for CSV cells where a quoted field like "Smith, John" needs to keep its internal comma while the field-separator commas around it are stripped or replaced.
Why did my number 1,000,000 lose its commas?
The Preserve commas inside numbers toggle is off. Turn it on and re-clean. Every comma flanked on both sides by a digit is then left alone.
Can I replace commas with a different character, not just space or newline?
This page covers the three most common cases (remove, replace with space, replace with newline). For custom replacements (semicolon, tab, pipe, emoji), use the Word Replacer tool which lets you set any find-and-replace rule.
I'm cleaning commas out of exported spreadsheet data before reimporting. Does my CSV get retained on your side?
No. Comma stripping runs in client-side JavaScript. The raw CSV you paste and the comma-free output both stay in this tab. We have no upload endpoint and don't keep a copy.
How do I do the opposite: turn a list into a comma-separated string?
Use the Column to Comma Separated tool. Paste one item per line, choose the separator (comma, comma+space, semicolon, custom), and copy the joined string. This is the inverse direction of the comma remover.
