Dear community,

I am trying to develope a code that needs to read and write .plt data due to storage reasons. Is there any way to import .plt data to python without the Tecplot license? I could use a macro to store all the data in ASCII format which is easily read by python but I would like to skip this step. Thank you in advance!

We do not publish an API to read PLT files. That said, our TecIO library *can* read and write SZPLT files.

You can convert PLT files to SZPLT, license free, using Tecplot 360 using the '-convert' flag. The TecIO library is distributed with Tecplot 360 and also available as a separate download. It's a C-based library and can be utilized from Python using 'ctypes'.

There's some example Python code on our GitHub page that shows out the TecIO API can be used to write SZPLT files. You should be able to follow the same pattern to implement the read functions.

I hope this helps. If you need additional assistance, please contact

You can check about it on google. On google search, you can easily find anything easily. I also use the google search engine when I want to find something. I tried the yahoo search engine or bing search engine but the algorithm of those search engines is not so good as compared to the google search engine. With the help of a google search, I easily found website where I found the best places to travel in Egypt for students. I am a college student and I am going on vacation with my friends to Egypt. It is my first time visiting over there and that is why I want to know the best places to travel in Egypt.
