Export activities to json?

[emilkarl]

Is there a way to export records to json?

[F3L1X79]

This is what I managed to do so far:

from fitparse import FitFile
import datetime
import sys
import json

fitfile = FitFile(sys.argv[1])

# Get all data messages that are of type record
records=[]
for record in fitfile.get_messages('record'):

    # Go through all the data entries in this record
    activities=[]
    activity_line={}
    for record_data in record:
        value = record_data.value
		
        if isinstance(value, datetime.datetime):
            value = record_data.value.strftime("%Y-%m-%d %H:%M:%S")
        if (record_data.name is 'position_lat' or record_data.name is 'position_long'):
            value = record_data.value * (180./2**31)
			
        activity_line[record_data.name] = value	
    records.append(activity_line)

# Make it work for Python 2+3 and with Unicode
import io
try:
    to_unicode = unicode
except NameError:
    to_unicode = str

# Write JSON file
with io.open('records.json', 'w', encoding='utf8') as outfile:
    str_ = json.dumps(records, indent=4, sort_keys=True, separators=(',', ': '), ensure_ascii=False)
    outfile.write(to_unicode(str_))
	
# Get all data messages that are of type lap
laps=[]
for record in fitfile.get_messages('lap'):

    # Go through all the data entries in this lap
    activities=[]
    activity_line={}
    for record_data in record:
        value = record_data.value
		
        if isinstance(value, datetime.datetime):
            value = record_data.value.strftime("%Y-%m-%d %H:%M:%S")
        if (record_data.name is 'position_lat' or record_data.name is 'position_long' or
        record_data.name is 'start_position_lat' or record_data.name is 'start_position_long' or
        record_data.name is 'end_position_lat' or record_data.name is 'end_position_long'):
            value = record_data.value * (180./2**31)
			
        activity_line[record_data.name] = value
    laps.append(activity_line)

# Make it work for Python 2+3 and with Unicode
import io
try:
    to_unicode = unicode
except NameError:
    to_unicode = str

# Write JSON file
with io.open('laps.json', 'w', encoding='utf8') as outfile:
    str_ = json.dumps(laps, indent=4, sort_keys=True, separators=(',', ': '), ensure_ascii=False)
    outfile.write(to_unicode(str_))

output={'records':records, 'laps':laps}
print json.dumps(output)

It creates a records.json and a laps.json files and output them as json array if needed.
