Extract text from ANNI network files (NNI)
To convert NNI network files to another format, you need ANNI Software or other Data software.
To convert other file formats to the "Machine Learning Model" file type, you need software like ANNI Software or a similar tool.
An .NNI file is a proprietary data format created by ANNI (Artificial Neural Network Investing) software to store trained machine learning models, financial market indicators, and historical trading data. Developed by Oolution Technologies, these files contain the specific weights and architectures used by Artificial Neural Networks to predict stock market movements.
Users frequently need to convert this file because the .NNI format is highly restrictive and heavily outdated. It is a closed, proprietary file that locks your financial data inside a single application. You cannot open it natively in modern data analysis tools like Python libraries, Microsoft Excel, or modern AI frameworks. Without the original, obscure software, the investing algorithms and historical data remain completely inaccessible.
The most practical conversion targets are CSV for tabular stock data, JSON for network architecture configuration, or TXT for raw data extraction. However, users should expect that proprietary algorithmic logic may be lost during extraction.
This file format is exceptionally difficult to open or convert because its underlying structure is undocumented. Often, only the original ANNI software can properly read or export the compiled trading rules. Our advanced analyzer can inspect the internal binary data of the .NNI file. If our analysis detects embedded plain text, XML data, or standard financial ticker symbols, viewing and partial data recovery may still be possible without needing the original software.
Convert.Guru analyzes your NNI file, detects the exact format, and lets you read the text inside.
Users also converted NNB, NNP and 7 files.
If you want to convert NNI file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use ANNI Software or similar software from the "Neural Network Investing 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 NNI, try ANNI Software or another comparable tool in the "Neural Network Investing 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 NNI converter.
