Assuming that you have stored your text in a variable named "txt". The following code should do what you want.
txt = regexprep(txt,'\r?\n',' '); %%replace carriage return and newline character with whitespace
pattern = {'(Date\s*\d{4}-\d{2}-\d{2})',...
'(Start\s*time\s*(\d{2}:\d{2}:\d{2}))',...
'(End\s*time\s*(\d{2}:\d{2}:\d{2}))',...
'(Acquired\s*time\s*(\d{2}:\d{2}:\d{2}))',...
'(Running\s*sequence\s*\w+)'};
output = regexpi(txt,pattern,'match');
output = cellfun(@(x) regexp(x,'\s(?=\d)|(?<=sequence)\s+','split'),...
output,'uni',0);
headerline = char(join(cellfun(@(x) sprintf('%-20s',x{1}{1}),output,'uni',0)));
values = char(join(cellfun(@(x) sprintf('%-20s',x{1}{2}),output,'uni',0)));
output_txt = sprintf('%s\n%s',strtrim(headerline),strtrim(values))
