About FSA_NT files

The .fsa_nt file is a text-based FASTA format file used by the NCBI GenBank and NCBI BLAST databases to store raw DNA and RNA nucleotide sequences. It represents nucleic acids using standard single-letter codes. You can open these files using a basic text editor or bioinformatics software like SnapGene and MEGA. However, the .fsa_nt format has strict practical limitations. It is a flat text format designed only to store the raw sequence and a single header line. It cannot store biological annotations, sequence alignments, or quality scores. Non-specialists often struggle to read the massive text blocks, and many modern genomic tools require specific file extensions rather than the niche .fsa_nt variant. To add rich annotations or metadata, convert your file to GB (GenBank) or GFF (General Feature Format). If your sequencing software rejects the file, converting or renaming it to a standard FASTA or FAS usually resolves the compatibility issue. For database management and spreadsheet analysis, convert the sequence data to CSV or TXT. Just drag and drop your file here to analyze and convert it - free, online, and without installing software.

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.
