Find and Replace Text in Documents

What is this page about?

This page describes how to find and replace text in Word documents with various matching options.

See more details in the Find and Replace article.

Use one of the Replace methods to find or replace a particular string within the current range. It returns the number of replacements made, so it is useful for searching strings without replace. An exception is thrown if a captured or replacement string contains one or more special characters: paragraph break, cell break, section break, field start, field separator, field end, inline picture, drawing object, footnote.

The following code example shows how to find some text and replace it:

Document doc = new Document("../../data/document.doc");

// Replaces all 'sad' and 'mad' occurrences with 'bad'.
doc.Range.Replace("document", "document replaced", false, true);

// Replaces all 'sad' and 'mad' occurrences with 'bad'.
doc.Range.Replace(new Regex("[s | m]ad"), "bad");
doc.Save("replacedDocument.doc");
