I'm trying to automate a process that replaces some values from a Word report template. I want to find a replace certain values and below is some code that I've tried but is not working
library(RDCOMClient)
wordApp <- COMCreate("Word.Application")
wordApp[["Visible"]] <- TRUE
newfile <- "~/test_updated_Test.docx"
doc <- wordApp[["Documents"]]$Open(normalizePath(newfile))
print(doc$range()$text())
[1] "Test 123 test\r"
# this does not work
x <- wordApp$ActiveDocument()$Content()
x$Find("Test 123 test", "test7")
<checkErrorInfo> 80020003
No support for InterfaceSupportsErrorInfo
checkErrorInfo -2147352573
Error: Member not found.
# this does not work either
wordApp$ActiveDocument()$Content()$Find("Test 123 test", "test7")
<checkErrorInfo> 80020003
No support for InterfaceSupportsErrorInfo
checkErrorInfo -2147352573
Error: Member not found.
I found the following solution :
library(RDCOMClient)
library(DescTools)
move_To_Beginning_Doc <- function(doc_Selection)
{
doc_Selection$HomeKey(Unit = wdConst$wdStory)
}
wordApp <- COMCreate("Word.Application")
wordApp[["Visible"]] <- TRUE
path_Original_Docx <- "C:/Users/xxx/original_document.docx"
path_Modified_Docx <- "C:/Users/xxx/modified_document.docx"
doc <- wordApp[["Documents"]]$Open(normalizePath(path_Original_Docx))
doc_Selection <- wordApp$Selection()
move_To_Beginning_Doc(doc_Selection)
# Replace = 2, Replace all occurrences.
# Replace = 0, Replace no occurrences.
# Replace = 1, Replace the first occurrence encountered.
# See https://learn.microsoft.com/en-us/office/vba/api/word.find.execute for the parameters of "Execute"
doc_Selection$Find()$Execute(FindText = "Apple",
Replace = 2,
ReplaceWith = "DiscountMod")
doc$SaveAs(path_Modified_Docx)
wordApp$quit()
