Remove Special Characters from Text Online

When you paste a list of emails, usernames, or URLs, they often contain unwanted characters: punctuation, symbols, dashes, underscores, or special markers that break validation or formatting. TextForge removes those characters in bulk — sanitizing hundreds or thousands of lines in seconds.

Why Remove Special Characters?

Special characters cause real problems:

Email lists — Trailing punctuation or dashes make addresses invalid.
Usernames — Many systems reject characters like @, #, !.
URLs — Extra punctuation or parameters pollute the domain.
Data imports — CSV parsers choke on unexpected symbols.
Security — Sanitizing user input prevents injection attacks.

Character Removal Options in TextForge

TextForge includes 58 text functions. These are the most useful for stripping characters:

Remove Punctuation

Strip commas, periods, semicolons, and other punctuation marks from every line.

Remove Numbers

Delete all numeric digits if your text needs to be text-only.

Remove Non-Alphanumeric

Keep only letters and numbers; strip everything else.

Remove Whitespace

Delete spaces, tabs, and line breaks to compact text.

Trim Whitespace

Remove leading and trailing spaces from every line.

Base64 Decode

Decode Base64 content to reveal the underlying text.

Real Example: Cleaning an Email Import

You export a list of contacts from an old system. The names have commas and periods, and email addresses have trailing punctuation:

Before — messy export

John, Smith | john.smith@example.com.
Dr. Jane (Sarah) Johnson - jane_johnson@example.com!
Mark O'Brien; mark.obrien@example.com?

After — sanitized

john.smith@example.com
jane_johnson@example.com
mark.obrien@example.com

Using TextForge: Extract Emails → Trim Whitespace → Remove Blank Lines.
