queXC takes a data file (such as data collected from a questionnaire) and cleans the text input fields (qualitative data or other textual data) by spacing them and spell checking them. queXC then allows operators to code the text to existing coding schemes, or to create a coding scheme on the fly. Multiple operators can code and clean simultaneously, including the ability to assign operators to do particular codes. The queXC system includes some coding schemes created from ABS (Australian Bureau of Statistics) data.

queXC can be used for to create hierarchical codings schemes for textual data, therefore in some instances can be used as an Open Source alternative to Nvivo. It is a survey research data cleaner and coder.


  • Import DDI and Fixed Width or CSV data files
  • Export DDI and Fixed Width, CSV or PSPP/SPSS data files
  • Multiple operators can code the same responses for comparison later
  • Option to automatically assign codes on exact match to code label or value
  • Can import a data file in parts based on an id column
  • Web based - only a browser required to operate
  • Create hierarchical coding schemes on the fly
  • Export/Import/Share coding schemes
  • Example coding schemes available
  • Entirely Open Source (requires only Open Source programs to operate)
  • Operators can refer difficult decisions to experts (supervisors)
  • Text to be coded can be selected and then assigned a code, and will be displayed alongside the code in the data (useful for listing quotes from data)
  • New in 0.9.2: Can code to multiple responses (multiple choice selection of codes)
  • New in 0.9.2: DDI v2.0 Data description editor

queXC makes use of the following Open Source technologies: (Thank you all for your great work)
