Find and replace in Word
Pick a .docx document and replace one piece of text with another throughout the document, keeping the formatting.
Ad space
The replacement happens right inside the document, so everything else stays the same: fonts, colors, tables, images, headers and footers (which are searched too). It finds the phrase even if parts of it have different formatting (for example, a bold word in the middle); in that case the new text takes the formatting of the start of the matched phrase.
