Assigning to the string in the string buffer (via stringstream::str or stringbuf::str) may lose the buffer already allocated by the string. Hi! Find the position of the first "0" using the SEARCH function and replace it with a "1" using the REPLACE function. Try this formula:

Every newline character ( '\n') triggers the repetition of the line and the clearing of the current string content.

To delete any n characters from the end of a string, please see How to remove characters from right in Excel.Is there a way to remove three words from an excel spreadsheet. the three words needing to be removed from each cell are all of different lengths but are all separated by a space Reply In terms of program semantics, one may only care that the stream "appears" and "behaves" as empty, similar to how a vector::clear may leave the capacity untouched but render the vector empty to the user (of course vector would spend just 16 bytes here). Given the memory allocation that string stream requires, I can imagine this approach being often faster. This answer's primary goal is to actually clear the string stream, given that memory consumption that comes with it is no joke. Depending on your use case (number of streams, data they hold, frequency of clearing) you may choose the best approach. Nest the above construction in the TRIM function, and you'll get a perfect formula to remove spaces before/after text as well as non-breaking spaces and non-printing characters:
