About FASTA files

The .FASTA file is the industry-standard text-based format for representing nucleotide (DNA/RNA) or peptide (protein) sequences. Originally developed for the FASTA software package, these files are essential for bioinformatics workflows involving alignment and homology searching.

However, the format's raw simplicity creates challenges: it is purely plain text, meaning it lacks visual formatting, annotation capabilities, or quality scores found in newer formats like FASTQ. Viewing large genomes in a standard text editor is unwieldy, and raw text is unsuitable for professional reports or publications. Users typically need to convert .FASTA files to PDF for readable, formatted archiving, CSV/Excel to organize header metadata, or NEXUS for phylogenetic software.

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

Users also converted FA, FAS, FSTA, FASTQ, FNA, TXT, GZ, AB1, ZIP, FAA, STATISTICS, PDF and CSV files.


FAQ

If you want to convert FASTA file to CSV, TXT, GENBANK, BAM, JSON, VCF, XML, YAML, YML, TOML, INI or CFG, you can use NCBI BLAST or similar software from the "Biological Sequence Storage" category. In the File menu, look for Save As… or Export….

To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to FASTA, try NCBI BLAST or another comparable tool in the "Biological Sequence Storage" category.



The FASTA 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 FASTA converter.
