Notes for reviewers (optional):

[TiffanyCheng27]

If the bool data x=1.0 or 0.0 then this convert function will return pd.NA
There might be a risk that csv save bool as float type and cause this error.
Can also consider to add trim value function for x_str

[scottbw]

I've pushed some changes to make boolean handling more robust.

Checked. All good
