Extract text from Genomic feature files (GFF)
To convert GFF Feature files to another format, you need Geneious or other Data software.
To convert other file formats to the "Bioinformatics Data File" file type, you need software like Geneious or a similar tool.
The .gff file extension primarily represents a Genomic Feature Format file (also known as Gene Feature Format). This is a standard plain text file used in bioinformatics to describe genes and other features of DNA, RNA, and protein sequences. Researchers rely on these files to map and annotate genomic datasets. Less common uses include firmware updates for The Genie Company, geospatial models from Topcon Positioning Systems, and data graphs in GraFit.
You can open genomic .gff files using specialized software like Geneious or AUGUSTUS, or by using a plain text editor like Notepad++.
The primary disadvantage of the .gff format is its rigid, highly fragile structure. It relies on a strict 9-column tab-separated system (including sequence ID, source, type, start, end, score, strand, phase, and attributes). Opening it in generic software, especially standard spreadsheet tools, often breaks the formatting, corrupts the columns, or alters genetic names into calendar dates. Furthermore, generic data analysis pipelines cannot process .gff files natively without writing custom parsing scripts.
To make this genomic data accessible, you must convert it. For general data science and spreadsheet review, convert .gff to CSV or TSV. For modern web applications and custom software integration, convert to JSON. Drag and drop your file to analyze and convert it - free, online, and without installing complex bioinformatics software.
Convert.Guru analyzes your GFF file, detects the exact format, and lets you read the text inside.
Users also converted GFF3, FNA, FASTA, TXT, PNG, JFIF, FSTA, ANN, BED, GENBANK, GBK, CSV and EMBL files.
If you want to convert GFF file to BED, GFF3, GENBANK, FASTA, GBK, CSV, EMBL, JSON, XML, YAML, YML or TOML, you can use Geneious or similar software from the "Genomic Sequence Annotation Data" 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 GFF, try Geneious or another comparable tool in the "Genomic Sequence Annotation Data" category.
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 GFF converter.
