How to keep single quote when importing Excel data to SAS



I am importing an Excel spreadsheet into SAS using Proc Import:


Proc Import out=OUTPUT
Datafile = "(filename)"
DBMS=XLSX Replace;
Range = "Sheet1$A:Z";
run;



My numeric data columns contain a mixture of values held in Excel as numerics and '0 values held as text - i.e. with a leading apostrophe / single quote. When SAS imports these it treats them all the same (i.e. it returns Character strings of the values with the leading apostrophe stripped out).



This results in differences from the spreadsheet when calculations are applied (e.g. averaging) as Excel treats the '0 values as missing but SAS treats them as 0.



Is it possible to import the values as strings including the leading single quote / apostrophe, so that I can replace the '0 with missing values but keep the 0 records as 0? I would like to avoid having to manually manipulate the data in Excel as this data is drawn from an external source (don't ask...)

I doubt it. I think Excel doesn’t really consider the leading apostrophe as part of the value. It’s just a crazy way to indicate that a value is a text string (rather than numeric). When SAS imports the data, it recognizes that the quote is not part of the value. So if you’ve got an Excel column with ‘0 in some cells and 0 in others, it’s going to come in as character, and I don’t think you can tell the difference between them.



Unfortunately, the xlsx engine doesn’t support the s DBSASTYPE option. Other engines that import Excel have the DBSASTYPE option. That should allow you to tell SAS to import a column as a numeric variable, even if it sees character values. If it’s the case that you want all text values in the cell converted to missing, that might do the trick. But it’s possible it would still treat ‘0 the same as 0. I’m away from SAS, so can’t test.

Clash Royale CLAN TAG #URR8PPP Arduino Mega cannot recieve any sketches, stk500_recv() programmer is not responding Yesterday we were trying to update the firmware of our 3D-printer a Tevo Tarantula i3 The printer was running Marlin 3D Printer Firmware. We installed a new module a TL-Touch Sensor, a chinese copy of the Bl-Touch an auto bedleveling touch sensor for a 3D printer. After re-configurating a new version of the firmware for our setup in the Arduino IDE we went on with uploading the sketch to the Arduino Mega that was controling our 3D printer. Before we started uploading we made sure the right COM-port was selected in the Arduino IDE and that also the right type of Arduino was selected. The Arduino Mega 2260. Then we started with compiling the firmware and then uploading it to the Mega, Somewhere in between that moment the IDE freezed and crashed. As a response we removed the USB cable that was connected from the PC uploading the firmware onto the Arduino Mega, (This was a st...

Clash Royale CLAN TAG #URR8PPP C++ virtual function: Base class function is called instead of derived I have following code snippet: using namespace std; class base { public: virtual void print(char a){ std::cout<<" Base "<<std::endl;} }; class derived :public base { public: void print(floata) {std::cout<<" Derived "<<std::endl;} }; int main() { base* d = new derived; d->print(1.5); return 0; } Output is "base" Why output is coming from base function and not from derived one By clicking "Post Your Answer", you acknowledge that you have read our updated terms of service, privacy policy and cookie policy, and that your continued use of the website is subject to these policies.
