I have been trying to figure out a way to automate my regression output such that each set of regression goes to a separate sheet in the same Excel document. In every cell of the final output there is, for example, ="0.067" and the stripquotes(yes) option gets rid of the quotes, but I am still left with the equal sign in every cell. Any ideas on how to get rid of it? I've tried the "plain" option with esttab, and while this gets rids of the = and the "", it gets rid of a lot of the other formatting.

// Regression set (1)
foreach v of varlist outcome_1 outcome_2 {

eststo: reg `v' x1 x2
eststo: reg `v' x1 x2 x3
eststo: reg `v' x1 x2 x3 x4

}

esttab using "$output\regressions_set_1.csv", ///
n se nobaselevels noconstant r2 aic bic replace ///
order(x1 x2 x3 x4) ///
keep (x1 x2 x3 x4) ///
label
estimates clear


// Regression set (1)
foreach v of varlist outcome_1b outcome_2b {

eststo: reg `v' z1 z2
eststo: reg `v' z1 z2 z3
eststo: reg `v' z1 z2 z3 z4

}

esttab using "$output\regressions_set_2.csv", ///
n se nobaselevels noconstant r2 aic bic replace ///
order(z1 z2 z3 z4) ///
keep (z1 z2 z3 z4) ///
label
estimates clear

// Read in each .csv and export excel so that I can automate getting
// all output on separate sheets in same document
foreach v in regression_set_1 regression_set_2 {
preserve
import delimited P:\Filepath\Regressions_`v'_final.csv, stripquotes(yes)
export excel using "P:\Filepath\Final_Results.xlsx", missing("")sheetreplace sheet("`v'")
restore
}
