ExcelTools:-Import("C:/Users/Usman/Desktop/Employees.xlsx", 1,"A1:B101");

Thanks @acer for your kind response. 

Location of file is C:/Users/Usman/Desktop/Employees.xlsx. I also attached this file. I want to plot 3 sheets.

Employees.xlsx.xlsx

@Preben Alsholm take p=0.1, L=8 and F(L)=G(L)=0 

Thanks @Preben Alsholm for your valuable suggestions. I know both equations have highest order is four. Is there any numerical method available to find the solution of above equations associated with 6 BCs.?

Dear @Kitonum I also attach the file from where I took the system of equation please see fix my problem please.

Dear @Kitonum  thanks for your valueable comment. How can I find the solution?

I used this command

fsolve([seq(`$`(F1[l1, l2], l1 = 2 .. 2^K*M-1), l2 = 2 .. 2^K*M), seq(`$`(F2[l1], l1 = 2 .. 2^K*M)), seq(`$`(F3[l1], l1 = 2 .. 2^K*M)), seq(`$`(F4[l1], l1 = 1 .. 2^K*M))]);
