About FSA_NT files

An .fsa_nt file is a specialized text-based data file used in bioinformatics to store nucleotide (DNA or RNA) sequences in the standard FASTA format. These files are typically generated by or used with the NCBI BLAST toolset to distinguish nucleotide databases from protein datasets. While the content is simple plain text, the obscure double extension often causes significant friction; operating systems like Windows and macOS do not recognize it, leaving users staring at an "Unknown File Type" error. Furthermore, many downstream bioinformatics tools and Python scripts strictly filter for standard extensions like FASTA or FA, meaning an .fsa_nt file might be rejected by your analysis pipeline despite containing valid data. To fix compatibility issues without altering the data, users typically convert these files to standard FASTA, or to TXT for quick editing in Notepad++. For archiving or sharing sequence data in a non-editable format, converting to PDF is the best practice.

Convert.Guru analyzes your FSA_NT file, detects the exact format, and lets you read the text inside.

Users also converted FNA, ASN and FSTA files.

The FSA_NT Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our FSA_NT converter.
