Extract text from TreePad databases (HJT)
To convert HJT databases to another format, you need TreePad or other Database software.
To convert other file formats to the "Legacy PIM Database" file type, you need software like TreePad or a similar tool.
A .HJT file is a hierarchical text database created by TreePad, a legacy personal information manager (PIM) developed by Freebyte. It stores personal notes, code snippets, and documents in a structured, tree-like node format.
TreePad is essentially abandonware. The original 32-bit software is unsupported and notoriously difficult to run natively on modern 64-bit operating systems like Windows 11 or macOS. Because .HJT is a proprietary file type, your historical notes and data are locked inside a rigid, outdated container. The format lacks native cloud synchronization, mobile application support, and compatibility with modern web browsers.
To recover your stored data, you must extract and convert it. For simple text retrieval across all nodes, convert to TXT. For importing your hierarchical notes into modern applications like Obsidian or Notion, convert to MD (Markdown) or XML. For archiving formatted text, use RTF. Drag and drop your file to analyze and convert it - free, online, and without installing obsolete software.
Convert.Guru analyzes your HJT file, detects the exact format, and lets you read the text inside.
Users also converted XML, SDOC and PMD files.
If you want to convert HJT file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use TreePad or similar software from the "Hierarchical Text Database" 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 HJT, try TreePad or another comparable tool in the "Hierarchical Text Database" 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 HJT converter.
