Can't load a file with -IMPORT EXCEL-

[Michael McCulloch]

I'm seeking to combine into one Excel file the results of two commands. In my complete code that follows:
1. The first command is TEFFECTS IPWRA, which can return stored results using -ESTIMATES TABLE- and -ESTTAB-.
2. The second is a post-estimation model fit test -TEBALANCE, OVERID-, which can return results using -RETURN LIST- and -PUTEXCEL-.

I've been successfully able to save the first command's results using -ESTTAB-, which only saves to *.csv Excel file format.
I've also been successful in saving the post-estimation command results using -PUTEXCEL-, which can only modify *.xlsx Excel files.

In order to modify the Excel file to add the p-value of the second command, I need to convert from *.csv to *.xlsx, but my code below returns error "file results2.csv could not be loaded" at that step. (I've confirmed correct directory, and that the file is not open.) Any advice would be appreciated.

results2.csv is not an Excel file, so -import excel- can't read it. It's a .csv file (which is a comma delimited text file), and to read it you need to use -import delimited-.

[Michael McCulloch]

Thank you Clyde!
-import delimited- can read the file just fine. I've studied the -help- file for -import delimited-, -import excel- and -export excel-, and don't see a way to avoid having each cell preceded by "=. Is there a workaround for this?

and don't see a way to avoid having each cell preceded by "=.

I don't know what you mean by this. Can you show some examples of what is happening?
