Left Justifying a String obtained from the formattedDisplayText() function

Hello, I asked a question here https://uk.mathworks.com/matlabcentral/answers/2173785-extracting-number-after-a-string-in-header-of-csv-file

about extracting header info from a CSv file and /Chris LaPiere kindly showed a way.

I often want to display info in a textarea rather than go and look in the command window and used this.

str = formattedDisplayText(header text,'SuppressMarkup',true,'LineSpacing','compact');

I then set the textarea text to this.

However, it doesn't appear left justified. I did also try this but it also had no effect

str=strjust(str,'left');

Is it even possible to get it left justified (in the textarea) - the header text begins at "Format "1.0B"

it does also appear like this in the command window

str = 
    "Format: '1.0B'
                   MemoryLength: 1000000
                   IntpDistance: 0
                 TriggerAddress: -51001
                   TriggerLevel: 2.3600
                         Source: 'CH1'
                  VerticalUnits: 'V'
               VerticalUnitsDiv: 0
         VerticalUnitsExtendDiv: 16

You would have to delete all leading space that occurs after any newline characters, e.g.:

str = regexprep(str,'^[ \t]+','', 'lineanchors')

or

spl = strtrim(strsplit(str,newline))

or similar.

Note that STRJUST does not justify each line (i.e. separated with newlines), it justifies the entire text as one (i.e. it only considers the leading/trailing whitespace of the entire text, not each line within the text).

thankyou,

this worked a dream

str = regexprep(str,'^[ \t]+','', 'lineanchors')

But this one didn't

spl = strtrim(strsplit(str,newline))

@Voss: thank you, fixed now!
