+## Sleep Data
+
+Export in javascript format.
+
+Use `=(A7/(1000*60*60*24)+25569)+(-4/24)` to convert javascript to date.
+
+Use the following table to convert `sleep` values to human-readable:
+
+| key | value       |
+| --- | ----------- |
+| 0   | unknown     |
+| 1   | not worn    |
+| 2   | awake       |
+| 3   | light sleep |
+| 4   | deep sleep  |
+
+Use `=VLOOKUP(<raw sleep value>,<cell with 0>:<cell with deep sleep>,2)` to convert number to human
+readable value.
+
+Use `=(<end date>-<start date>)*1440` to calculate minutes between each timestamp.
