How to import a part of an Excel file?

I'm trying to import a part of an excel, the column 20 and the row between 6-59 in this column. I tried :

tab = Import[
"file.xlsx"];
time = tab[[20, 6 ;; 59]]


and

time = Import[
"D:\Users\martine\Desktop\data\KP\Results largest GFP area \
mean.xlsx", {"Data", 1, {6;; 59}, {20}}]
time = Import[
"D:\Users\martine\Desktop\data\KP\Results largest GFP area \
mean.xlsx", {"Data", 1, {6:59}, {20}}]


But it doesn't work so apparently I didn't write it the right way.

• try {"Data", 1, 6;; 59, {20}}? – kglr Jun 14 at 8:40
You should remove the braces around Span in the second argument of Import, that is, use
{"Data", 1, 6;;59, {20}}
