Yes, that the direction I have to go. Thanks so much. It gets really hairy
with some of the notations.

Like a variable for DustNum >0.3 (micron), that variable name became two
columns, ">0"0 and  "3DustNum"

I will have to become a spreadsheet jockey (again) about 40 yrs later...

The spreadsheet I sent gave columns A thru AB, but some may not have
separated exactly correct. Not knowing exactly what changes would be needed.
Started by inserting a row at top.
To convert date to an actual date field. In ad1 put B.
In ad2 put this formula to make a date.
=DATE(LEFT(B2,4),MID(B2,5,2),RIGHT(B2,2))
In ae1 put D
In ae2 put
=TIME(INT(D2/100),MOD(D2,100),0)

wow... I had never used that function before...

I am not quite there yet, however, but at least this is a path. Here
is an
example of one of the strings

Date:20220302 Time:1631 PM1.0:000 PM2.5:000 PM10:000 CO2:0010
HCHO:0.001
TVOC:0.000 >0.3DustNum:00000 >0.5DustNum:00000 >1.0DustNum:00000
2.5DustNum:00000 >5.0DustNum:00000 >10DustNum:00000

Using the expression as you wrote it, I get fields, like this:
Date 20220302 Time 1631 PM1.0 000 PM2.5 000 PM10 000 CO2 0010 HCHO
0.001
TVOC 0.000 >0.3DustNum 00000 >0.5DustNum 00000 >1.0DustNum 00000
2.5DustNum 00000 >5.0DustNum 00000 >10DustNum 00000 and then I could
name the columns and delete the columns with the variable names.

I will have to study that function... thanks.

Place the strings in column 1 than put

=REGEX($A1,"(?<=^| |:)[^ ]+?(?=:| |$)",,COLUMN()-1)

in column 2 and drag right for ten columns and down.
