File format where column names are repeated on each row I have received a dataset in text file with the following format

col1=datac1r1,col2=datac2r1,col3=datac3r1
col1=datac1r2,col2=datac2r2,col3=datac3r2
col1=datac1r3,col2=datac2r3,col3=datac3r3
col1=datac1r4,col2=datac2r4,col3=datac3r4


Each row is a unique entry, with columns separated by comma, just that the column name is repeated in each element. 

I need to parse this in R and analyze it. I have worked with csv files extensively, but I have never seen this format before. 

Is it a std. format I can import it in? Or do I need to write a script to convert it into a csv format?

you will have this CSV

col1,col2,col3
datac1r1,datac2r1,datac3r1
datac1r2,datac2r2,datac3r2
datac1r3,datac2r3,datac3r3
datac1r4,datac2r4,datac3r4
