Extract text from Tesseract OCR models (TRAINEDDATA)
To convert TRAINEDDATA OCR models to another format, you need Tesseract OCR or other Data software.
To convert other file formats to the "Machine Learning Model" file type, you need software like Tesseract OCR or a similar tool.
The .traineddata file format is a combined language dataset used by Tesseract OCR, a powerful open-source Optical Character Recognition engine. These files store pre-computed machine learning weights, character sets, and dictionaries needed to identify specific languages or fonts within images.
A major disadvantage of the .traineddata format is its highly specific, compiled binary structure. You cannot simply open these files in a text editor to view the trained characters or edit the language rules. They are rigid and completely useless outside of the Tesseract ecosystem. Users generally encounter these files when attempting to add support for a new language or when fine-tuning a custom OCR model.
Because this is a compiled machine learning model, standard online converters fail to process it. You cannot convert a .traineddata file into a PDF or DOCX document. Developers sometimes seek to migrate these models to other neural network frameworks like ONNX or TensorFlow, but this requires specialized Python scripts rather than simple file conversion.
This file format is difficult to open or convert because only the original Tesseract command-line tools can properly read, pack, or unpack the data. Just drag and drop your file into convert.guru to identify the format, view its internal metadata, and extract readable text. If our analysis detects a supported underlying or embedded format, viewing or data extraction may still be possible.
Convert.Guru analyzes your TRAINEDDATA file, detects the exact format, and lets you read the text inside.
Users also converted GZ and J2S files.
If you want to convert TRAINEDDATA file to , you can use Tesseract OCR or similar software from the "OCR Language Data Model" category. In the File menu, look for Save As… or Export….
To convert files to TRAINEDDATA, try Tesseract OCR or another comparable tool in the "OCR Language Data Model" 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 TRAINEDDATA converter.
