What is an ABI file?
An .ABI file can hold different types of data depending on the software that created it. The most common type is a DNA sequencing chromatogram file. These files store sequence data generated by Applied Biosystems DNA sequencers. Another common format is the Application Binary Interface for the EOSIO blockchain platform. This file acts as a bridge between smart contracts and user applications. Less commonly, an .ABI file might be an AOL Address Book Index or a plugin for the AbiWord word processor.
How to open ABI files?
Because .ABI files have multiple completely different uses, you need the right tool for your specific file. Biologists use bioinformatics software like FinchTV, SnapGene Viewer, or Python libraries like Biopython to read DNA chromatograms. If your file is an EOSIO smart contract, you can open it with standard code editors like Visual Studio Code because it often uses JSON text formatting. Legacy AOL files require older address book tools.
Identify and inspect your file
If you do not know which type of .ABI file you have, viewer.online/abi can analyze .ABI files to identify the exact format and creator software. It allows you to inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
viewer.online/abi is useful for identifying, inspecting, and understanding .ABI files without installing software or dealing with compatibility problems.
