How to Reverse Words in Word (Microsoft Word Tutorial)

Microsoft Word provides extensive formatting tools, yet it curiously lacks a dedicated button to reverse words or flip sentence word order. When editors and students search for how to reverse words in word or need to reverse text in word, they often struggle with tedious manual cut-and-paste operations.

Fastest Solution: Browser Inversion

Instead of creating cumbersome VBA macros in Word, simply copy your text paragraph, paste it into this app that reverses words, click Copy, and paste the neatly reversed words back into Microsoft Word in less than 3 seconds.

Microsoft Word VBA Macro Method

For automated document templates inside Word, developers can insert this VBA macro into a Module:

Sub ReverseSentenceWordOrder()
    Dim words() As String
    Dim result As String
    Dim i As Long
    words = Split(Selection.Text, " ")
    For i = UBound(words) To LBound(words) Step -1
        result = result & words(i) & " "
    Next i
    Selection.Text = Trim(result)
End Sub

Algorithmic Complexity & Coding Interviews: Reverse Words in a String

Reversing words in a sentence is one of the classic LeetCode / technical interview problems (LeetCode 151). The challenge requires transforming an array of characters with O(n) linear runtime complexity and O(1) extra auxiliary memory space.

// JavaScript - Linear time word order reversal
function reverseWordOrder(str) {
    return str.trim().split(/\s+/).reverse().join(' ');
}

# Python - High performance slice reversal
def reverse_words_python(s: str) -> str:
    return ' '.join(reversed(s.split()))

// C++ - Two-pointer in-place reversal
void reverseWords(string &s) {
    reverse(s.begin(), s.end()); // Step 1: Reverse whole string
    int n = s.size(), l = 0, r = 0;
    while (r < n) {              // Step 2: Reverse each word
        while (r < n && s[r] != ' ') r++;
        reverse(s.begin() + l, s.begin() + r);
        l = ++r;
    }
}
