## About this Block

**What it does:**

**Common uses:**

* This block converts the text list output from the **Extract Column** block to a scalar list.

**Tips:**

* This block will process text lists into scalar lists.
* Units will not be recognized and will cause conversion issues.
* No punctuation other than periods or letters are allowed.
* If using exponential notation, ensure no spaces exist before or after the letter `e`.
* Positive and negative exponents are allowed.
