What is Lattice QDA?

Lattice is a free and open-source Computer-Assisted Qualitative Data Analysis Software (CAQDAS). Built with the Lazarus IDE and Free Pascal Compiler, it is designed to be native, lightweight, fast, and scalable, with no heavy frameworks or dependency trees.

Every project is a portable ‘.lattice’ file (SQLite database). Documents can be imported from TXT, DOCX, ODT, PDF, XLSX, ODS, JSON, and SQLite sources. Typed attributes (Text, Categorical, Numeric, Date-Time, and URL or Path) enable richer filtering and analysis.

The code tree supports up to six levels of hierarchy. Five memo types capture reflections at the project, document, code, and segment levels, alongside free-floating analytical memos. The Retrieval Manager exports coded segments to PDF and HTML reports, as well as structured data formats. The Analysis Workspace includes Code Frequency, Code Co-occurrence, Attribute-Code Crosstab, Coding Coverage, and Word Cloud analyses, with visualisation exports in SVG, PDF, PNG, and JPEG.
