Work-search log: how detailed does it need to be?

I am keeping a spreadsheet of applications, but I worry it is not what the agency expects. I do not usually post, so bear with me. My state says to keep records for a year.

I record the date, the company, the job title, how I applied and any contact name. It takes a minute each and it covered me when I was asked for proof.

I was asked for my log once, after six months. Having it in a spreadsheet made it painless.
