For eg.
Input
1 23354
2 345344
3 43543553
Output
1 23354 T
2 345344 C

If could reformat your excel file to BED format (even within excel) and save it as plain text (say as mypositions.bed). Then, you can use bedtools as something like (assuming you have already the FASTA file for hg19):
Code:
bedtools getfasta -fi hg19.fa -bed mypositions.bed -tab
