CSIJSON
CSIJSON files contain header information and data in a JSON
format.
Example:
"signature": 38611,"environment": {"stationfiname": "11467","tablefiname":
"Test","model": "CR1000","serialfino": "11467",
"osfiversion": "CR1000.Std.21.03","progfiname": "CPU:file format.CR1"},"fields":
[{"name": "battfivoltfiMin","type": "xsd:float",
"process": "Min"},{"name": "PTemp","type": "xsd:float","process": "Smp"}]},
"data": [{"time": "2011-01-06T15:04:15","no": 0,"vals": [13.28,21.29]},
{"time": "2011-01-06T15:04:30","no": 1,"vals": [13.28,21.29]},
{"time": "2011-01-06T15:04:45","no": 2,"vals": [13.28,21.29]},

Data File-Format Elements
HEADER
File headers provide metadata that describe the data in the file. A TOA5 header
contains the metadata described below. Other data formats contain similar
information unless a non-header format option is selected in the TableFile()
instruction in the CR3000 CRBasic program.
Line 1 – Data Origins
Includes the following metadata series: file type, station name, CR3000
model name, CR3000 serial number, OS version, CRBasic program
name, program signature, data‐table name.
Line 2 – Data-Field Names
Lists the name of individual data fields. If the field is an element of an
array, the name will be followed by a comma‐separated list of
subscripts within parentheses that identifies the array index. For
example, a variable named “values” that is declared as a two‐by‐two
array, i.e.,
