Exonic SNPs extraction

Hi, I have a list of SNPs from a custom made microarray based on hg19/gb37. I need to extract all SNPs that are located in exons throughout whole genome. Is there a simple way to do this? Thanks in advance for your help

If you have rs number then may be you can use annotation based tools like wAnnovar, SNP nexus or VEP. These will exonic SNPs.

intersect gtf with bedtools.

There are some programs that, having a gtf or gff file with your annotations, let you to extract regions of your genome. One of such programs is rgmatch

Thanks everyone for the answers. I don't think I have all the information required to generated gff (or GTF) file (https://genome.ucsc.edu/FAQ/FAQformat.html#format4) so I am not sure how to go about it. The SNP lists I've been dealing with have #rs (some with custom designations), chr, chr pos and genotyping data. In the past I used batch query in dbSNP but this is now defunct. If there is already workable solution (not involving programming) I would be grateful for a link. Apologies if this comment is duplicated as I haven't completely 'mastered' biostars system yet.
