Simple Google Go (Golang) library for replacing text in Microsoft Word (.docx) file
The following constitutes the bare minimum required to replace text in DOCX document.
package main
import (
"strconv"
"github.com/nguyenthenguyen/docx"
)
func main() {
// Read from docx file
r, err := docx.ReadDocxFile("./TestDocument.docx")
// Or read from memory
// r, err := docx.ReadDocxFromMemory(data io.ReaderAt, size int64)
// Or read from a filesystem object:
// r, err := docx.ReadDocxFromFS(file string, fs fs.FS)
if err != nil {
panic(err)
}
docx1 := r.Editable()
// Replace like https://golang.org/pkg/strings/#Replace
docx1.Replace("old_1_1", "new_1_1", -1)
docx1.Replace("old_1_2", "new_1_2", -1)
docx1.ReplaceLink("http://example.com/", "https://github.com/nguyenthenguyen/docx", 1)
docx1.ReplaceHeader("out with the old", "in with the new")
docx1.ReplaceFooter("Change This Footer", "new footer")
docx1.WriteToFile("./new_result_1.docx")
docx2 := r.Editable()
docx2.Replace("old_2_1", "new_2_1", -1)
docx2.Replace("old_2_2", "new_2_2", -1)
docx2.WriteToFile("./new_result_2.docx")
// Or write to ioWriter
// docx2.Write(ioWriter io.Writer)
docx3 := r.Editable()
//Currently only swaps apples for apples i.e. png to png, and not png to jpeg etc.
docx3.ReplaceImage("word/media/image1.png", "./new.png")
// replace the last image
imageIndex := docx3.ImagesLen()
docx3.ReplaceImage("word/media/image"+strconv.Itoa(imageIndex)+".png", "./new.png")
docx3.WriteToFile("./new_result_3.docx")
r.Close()
}
