is_A1 FALSE if number too big -> read_excel doesnt work

[Droelf-source]

Hello,

I noticed that my range given in A1 format doesn't work with read_excel if the number of rows is bigger than 100,000. I think the only problem is that the is_A1(x) check fails. Curiously, if I try

cellranger::is_A1("$A$636026")
FALSE

but if I copy the code from the github repository

.cr <- new.env(parent = emptyenv())
.cr$A1_rx <- "^\$?[A-Za-z]{1,3}\$?[0-9]{1,7}$"
is_A1 <- function(x) { grepl(.cr$A1_rx, test)}
is_A1("$AA$636026")
[1] TRUE

it does work. Now if I try to read in excel files using a range with more than 100,000 rows it stops and says it isn't in A1 format.

Also the breakpoint is in fact 100,000

cellranger::is_A1("$A$100000")
[1] FALSE
cellranger::is_A1("$A$99999")
[1] TRUE

For now I can workaround this issue by replacing the function with the copied code from github but I think it is kinda an interesting as I have no idea how it doesn't work as is.

Best Regards
