I need to remove the units within brackets from my CSV file, attached.
ID par1 (mol) par2 (meter^3) par3 (kg/L)
1 4 5 11
2 3 6 10
3 2 7 9
4 1 8 8
here the basic code I tried
data = readtable('headerFile.csv','ReadVariableNames', true);
headerRow = data.Properties.VariableNames
readtable however messes up the header (raplaces special characters with '_') and instead of
{'ID'} {'par_1 (mol)'} {'par_2 (meter^3)'} {'par_3 (kg/L)'}
I get
headerRow =
1×4 cell array
Columns 1 through 4
{'ID'} {'par_1_mol_'} {'par_2_meter_3_'} {'par_3_kg_L_'}
What is the best way to extract the actual header?

Ran in:
data = readtable('headerFile.csv','ReadVariableNames', true, 'VariableNamingRule','preserve')
data = 4×4 table
ID par_1 (mol) par_2 (meter^3) par_3 (kg/L) __ ___________ _______________ ____________ 1 4 5 11 2 3 6 10 3 2 7 9 4 1 8 8

hello
here you are :
headerRow = {'ID'} {'par_1 (mol)'} {'par_2 (meter^3)'} {'par_3 (kg/L)'}
data = readtable('headerFile.csv','ReadVariableNames', true,'VariableNamingRule' , 'preserve');
headerRow = data.Properties.VariableNames
