I don't see why you would use RegEx for this. &nbsp;Almost all languages have a &quot;replace&quot; function, just use that, like below. &nbsp;Much faster and simpler...<br />

A regular expression replacement would just use a single space as the pattern, and an empty string as the replacement. If you also wanted to replace line feed, newline and tab characters, the pattern would be \s

Regular Expression to remove all spaces

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.
