I get the corruption error when I try to open the Excel workbook created in R.
I tried with both .xlsx and .xls extensions but neither worked!
The code that I used for doing all this is:
wb <- loadWorkbook("RCreated.xls", create = TRUE);
saveWorkbook(wb)
createSheet(wb, name = "First")
HELP!
Create the sheet BEFORE saving the workbook.

I have a function that receives DataFrame does a bunch of transformations with openxlsx and exports the data from R to .xlsx:
export_workbook_from_df <- function(data, path) {
wb <- openxlsx::createWorkbook()
openxlsx::addWorksheet(wb, sheetName = "Sheet1")
openxlsx::openxlsx_setOp("numFmt", "0,00")
number_format <- openxlsx::createStyle(numFmt = "Number") # create thousands format
wb |>
openxlsx::addStyle(sheet = 1,
number_format,
rows = 1:nrow(dados) + 1, cols = c(6),
gridExpand = T
)
openxlsx::writeData(wb, sheet = 1, data)
openxlsx::saveWorkbook(wb, paste0(path, ".xlsx"))
}
if I try to save as .xls using openxlsx::saveWorkbook(wb, paste0(path, ".xls")) I get the following error:
Which roughly translates to:
The format of the file and the extension don't correspond. The file may be corrupted or not be safe. Don't open it, unless you trust the source. Do you want to open anyway?
The file works fine if I save it as .xlsx and manually save as .xls within Excel;
I also tried using XLConnect to load the file after is saved and export in a different format, like:
openxlsx::saveWorkbook(wb, paste0(path, ".xlsx"))
XLConnect::loadWorkbook(paste0(path, ".xlsx")) %>%
XLConnect::saveWorkbook(paste0(path, ".xls"))
While it does export the file as .xls I get the same error.
It may be worth mentioning that when I open the file I get exactly the same data as in the .xlsx file when using either methods (using openxlsx and XLConnect)
The xls and xlsx file formats are not the same: XLSX is a zipped, XML-based file format. Microsoft Excel 2007 and later uses XLSX as the default file format when creating a new spreadsheet. Support for loading and saving legacy XLS files is also included. XLS is the default format used with Office 97-2003. When you try to load the XLSX which you saved as an XLS Excel barfs as above because it is expecting the old binary format but it is encountering a zipped XML-based one instead.
I have an xlsx workbook on my desktop with existing sheets. I have a dataframe in R that I would like to add to this workbook as a new sheet.
Using library(openxlsx) I want to do:
wb <- loadWorkbook("workbook.xlsx", isUnzipped=TRUE)
addWorksheet(wb, "New_Sheet")
writeData(wb, "New_Sheet", df)
saveWorkbook(wb, "workbook.xlsx", overwrite=TRUE)
however the program fails at the first line:
wb <- loadWorkbook("workbook.xlsx", isUnzipped=TRUE)
I get the error message:
Error in match(sheetrID, file_rIds): object sheetrId not found
I also created a dummy file (excel workbook with just two existing sheets and some dummy strings in each sheet) and I get the same error message.
I also tried uninstalling openxlsx and re-installing. No change.
As mentioned in the comments by #MrFlick (thank you!), Excel files are actually zipped files that contain XML files. So the workbook must be unzipped before it can be opened in R.
I am trying to manipulate an Excel file (.xls) in R through RDCOMClient Package.
I created an Excel object in R, opened a workbook saved as .xls file format, and tried to convert the file format into .xlsx without pop-up dialog box when there is an Excel file with the same file name. Codes as below.
excel <- COMCreate("Excel.Application")
wb <- excel$Workbooks()$Open(Filename = "filepath.xls",Password = "xxxxx")
excel$DisplayAlerts(FALSE)
wb$SaveAs(Filename = "filepath.xlsx" ,FileFormat = 51,Password = "")
I got an error message when I executed the code:
excel$DisplayAlerts(FALSE)
<'checkErrorInfo'> 8002000E Error: invalid number of parameter.
You should replace it with the following:
excel[["DisplayAlerts"]]=FALSE
As the title stated, I would like to delete the second worksheet in excel using r with package xlsx. However, after running the code, nothing happened. Following is a sample code I used to delete the sheet:
path = "C://ECOS//Code//Test//data.xlsx"
sheets = getSheets(loadWorkbook(path))
removeSheet(loadWorkbook(path), sheetName = names(sheets[2]))
Really appreciate helps. Thank you!
You need to save the workbook in the same file (or different if you prefer).
wb = loadWorkbook(path)
removeSheet(wb, sheetName = names(sheets[2]))
saveWorkbook(wb, path)
I am trying to change the page setting of a xlsx file so that it will be printed as landscape, but not portrait, I tried the following:
library(xlsx)
wb <- createWorkbook()
sheet <- createSheet(wb, "Sheet1")
ps <- printSetup(sheet, landscape=TRUE, copies=3)
This is OK if I create a new Excel workbook, but I can't use it when I am using the loadWorkbook function to load an xls file. I wonder why.
Update: I am working on a xls file but not xlsx file and found the answer below cannot solve my problem, any further suggestions? Thanks.
I can get it to work by using getSheets to select the sheet to set the print area for:
wb <- loadWorkbook("test.xlsx")
printSetup(getSheets(wb)[[1]], landscape=TRUE, copies=3)
saveWorkbook(wb,"test.xlsx")
