Crystal FLOW – Code To Flowchart

Crystal Flow is a flowcharting tool that generate flowcharts from C/C++ source code. It is also very useful for programmers trying to interpret code written by others. The flowcharts generated in this instance help coders to understand layers of nested variables.

  • Automatic Flowcharts – Crystal FLOW automatically creates flowcharts from source code.
  • Detail – Each flowchart symbol contains detailed code within it, so users do not have to keep flicking between windows.
  • Comment-based flowcharts - Alternatively comment-based flowcharts can be generated, which are also useful to programmers and test engineers.
  • Export – Flowcharts can be exported in either .bmp or .jpg formats.


There are two different Crystal FLOW downloads available, depending on whether you require an application for C or for C++. The C (V4.65) download costs $109 for a Single User licence. The cheapest C++ (V4.65) download costs $124.

Either of these programs can be downloaded at this address.


This is a great time-saving tool, especially for new team members on a coding project. Quickly get a visual representation of the code structure, instead of spending up to an hour building up your own interpretation.
