About ARB files
The .ARB file extension represents a diverse set of data formats, creating significant confusion for users. The most common modern usage is the Application Resource Bundle, a JSON-based localization format used by the Google Flutter framework to manage app translations. While convenient for developers, sending raw .ARB files to non-technical translators is problematic; they require specialized editors or manual syntax management. Converting these to CSV, XLSX (Excel), or XLIFF allows translators to work in standard environments without breaking code structure.
In scientific and industrial sectors, .ARB refers to completely different binary formats. In bioinformatics, it is a sequence database used by the ARB Project for ribosomal RNA analysis, which is strictly tied to Linux environments and difficult to share with colleagues using standard office software. In manufacturing, it functions as a dataset for Arburg injection molding machines (Selogica control systems). These proprietary binary files are often illegible outside their specific hardware or costly OEM software. For developer files, the best workflow is converting to JSON or Excel for editing. For scientific data, exporting to FASTA or TXT ensures accessibility.
Convert.Guru analyzes your ARB file, detects the exact format, and lets you read the text inside.
If you want to convert ARB file to FASTA, ADB, JSON, MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF or OPUS, you can use Google Flutter or similar software from the "Localization Resource Bundle" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to ARB, try Google Flutter or another comparable tool in the "Localization Resource Bundle" category.
The ARB 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 ARB converter.
