Koopax OpenFormat
A free tool for reading the Israeli Tax Authority's open-format files (מבנה אחיד), under Instruction 131 — straight in the browser, with no software to install.
Why use the tool?
Features built around what accountants, system administrators and businesses actually need when working with open-format files.
Handles large files
Works with files over 4MB too — convenient for day-to-day work with long reports and exports.
Automatic encoding detection
The tool works out the file's encoding so the content comes out readable and correct, with no manual fiddling.
The tool — open a file and get going
The full Koopax OpenFormat interface is embedded here. If it loads slowly, you can open the tool in its own tab.
Open source, and back to the site
Koopax OpenFormat is part of the Koopax open-source effort — building open tools that serve every register on the market, not only Koopax customers. The project is on GitHub, where you can read the code, report issues and contribute. For Koopax sales and support, head back to the home page or get in touch.
