Randomization without consecutive critical items

Thank you for the response.
Yes, I do need the randomization.I have 32 critical items and 64 control items, and every participant in the experiment should get a different order.

I read the following post, but I do not know how to use it for mine.: Randomisation with constraints - #9 by JensBoelte

The way I understood this is

  1. import the stim xlsx.
  2. randomize the order of the stims.
  3. put the logic to say “i and i +1 or i and i - 1” should not have the same label in Type such as Critical, otherwise randomize the order of the stim.
  4. when it satisfies the logic in 3, it starts the experiment.

Here is the dataframe again:
Data frame in excel file is like this:
Item Type Stimulus
1 Critical sentence1 …
2 Critical sentence2…
3 Critical sentence3 …
4 Control sentence4 …
5 Control sentence5 …
6 Control sentence6 …
7 Control sentence7 …
8 Control sentence8 …
…
so on
…
96 Control Sentence96

But I do not know how to code them, can you help with this? step by step?
