I'm trying to download a .zip file from a url and extract a .xls to read it.

while download the zip file and extract it was a simples task, i wasn't able to read it, everytime i try to read the .xls file i get the following error message:

I think I can confirm @r2evan's diagnosis. I unzipped the file, opened it and re-saved to a different file using OpenOffice, and was then able to use readxl::read_excel() to read the file.

Note that the file also has "interesting" structure at the beginning - hierarchical/merged labels - that you'll have to deal with as well, the simplest solution would be to skip the first 4 rows and add your own column names manually, although all of these problems [except the one you initially posed of unreadability] can be solved programmatically if you're willing to work hard enough.

This question lists related problems and potential solutions, although the easy ones don't seem to work: there is one programmatic solution there (using OpenOffice command-line tools), everything else is "open it and re-save it with Excel/OpenOffice".

gdata::read.xls() opens the original file successfully but then hits "invalid multibyte string"
XLConnect::readWorksheetFromFile("Tab_Compl_CNT_1T21.xls"):

How to reference a worksheet when creating a libref?

I am new at SAS and I am trying to create LibRef using an *.xls file. The Excel file has four worksheets: Sheet1, Sheet2, Sheet3 & Sheet4. How do I tell the libref to reference "Sheet1" only?

AFAIK that isn't possible. You set up the libname as a connection to the Excel file (usually XLSX these days, not XLS) and then you can reference the Sheet as you would a data set.

I am not sure why it is happening but when I try to open the .xls file manually, it gives an error like "The file format and its extension does not match" etc. To solve the issue, I converted the file extension to .csv with the codes below.

I am trying to create a package to download, import and clean data from the Dominican Republic Central Bank web page. I have done all the coding in Rstudio.cloud and everything works just fine, but when I try the functions in my local machine they do not work.

After digging a bit on each function, I realized that the problem was the downloaded file, it is corrupt.

I am including the first steps of a function just to illustrate my issue.

From the Documentation of download.file()

The choice of binary transfer (mode = "wb" or "ab") is important on Windows, since unlike Unix-alikes it does distinguish between text and binary files and for text transfers changes \n line endings to \r\n (aka CRLF).

Code written to download binary files must use mode = "wb" (or "ab"), but the problems incurred by a text transfer will only be seen on Windows.
