Hi Wenxin,

Save your Excel file as a space delimited text file in BED format 
(http://genome.ucsc.edu/FAQ/FAQformat.html#format1), e.g.:

chr21 32986714 33086453
chr7  27210211 27213955
chr3  32986714 33086453
chr5  27210211 27213955

Then upload that file as a custom track 
(http://genome.ucsc.edu/cgi-bin/hgCustom).

Next go to the table browser (http://genome.ucsc.edu/cgi-bin/hgTables), 
select your custom track, set region to 'genome', output format to 
'sequence' and get output. The resulting file will contain the sequence 
of the uploaded positions.

Please let us know if you have any additional questions: [email protected]
