The table has twenty-six rows and seven columns: date, time, a Before tick, an After tick, the reading, the insulin or medicine you took, and a wide notes column for the meal, the walk or the illness that sits behind the number. Choose mg/dL or mmol/L before you download and the reading column header prints that unit, so nobody reading the sheet later has to guess which scale you were using.
Nothing on the page is a target. There is no printed range, no colour coding and no good-or-bad column, because the numbers to aim for depend on you, on your treatment and on your clinician. Instead the header has a line where you write the readings and times your diabetes team actually asked you to record, so the instruction travels with the log rather than living in your memory.
Every cell is a form field, so you can type the week up on a laptop and print a filled sheet, or print it blank and write at the kitchen table. It is one page in US Letter or A4, drawn as vector lines that stay crisp on any printer, with rows spaced for handwriting. Print a stack and keep them in a folder with your meter, and take the pages to your appointment: a written record over weeks shows a pattern that a meter's memory rarely makes obvious.
