ResourceFunction["ByteArrayToBitList"][ba]

converts ByteArray ba to a list of bits.

Details and Options

The output typically requires 64 times more memory than the input.

Create a byte array:

In[1]:=

Out[1]=

Convert to individual bits:

In[2]:=

Out[2]=

Compare the number of bytes needed to represent the expressions:

In[3]:=

Out[3]=

For larger bit arrays the relative memory expansion does approach a factor of 64:

In[4]:=

Out[6]=
