Using Regex in Google sheets, I need to extract "content1" in a separate cell (B1) from the 1st bracketed set without the brackets
This entire string will appear in cell A1: [content1] [content2][content3] [content4][content5]
The content in the brackets will vary in length and may contain symbols and/or numbers (ex:"JPS | 5")
There will always be 5 bracket sets
