What is GenBank to FASTA?

GenBank to FASTA converter extracts DNA, RNA, or protein sequences from GenBank format files and converts them to FASTA format. This tool parses GenBank entries to extract the sequence data from the ORIGIN section and creates proper FASTA headers from the LOCUS information.

How to Use This GenBank to FASTA Converter

Convert GenBank files to FASTA in three simple steps:

1. Paste your GenBank format data or upload a .gb file
2. Results appear automatically in FASTA format
3. Download or copy the converted sequences

When to Use
