I have already loaded the data in R from various sheets, below you can see the names of the sheets. Below you can see the data and code:
df<-data.frame(
Tables=c("Export_A1.xlsx","Export_A2.xlsx","Export_A10.xlsx"))
So now I want to extract specific names, or in other words, I want to remove the text "Export_" and ".xlsx". Below you can see an example
So can anybody help me how to solve this problem ?

You can use the following code:
df$Tables <- gsub(".*[_]([^.] )[.].*", "\\1", df$Tables)
df
Output:
Tables
1 A1
2 A2
3 A10
