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.
