A data logger (also datalogger or data recorder) is an electronic device that records data over

time or in relation to location either with a built in instrument or sensor or via external instruments
and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer).
They generally are small, battery powered, portable, and equipped with a microprocessor,
internal memory for data storage, and sensors. Some data loggers interface with a personal
computer, and use software to activate the data logger and view and analyze the collected data,
while others have a local interface device (keypad, LCD) and can be used as a stand-alone
device.
Data loggers vary between general purpose types for a range of measurement applications to
very specific devices for measuring in one environment or application type only. It is common for
general purpose types to be programmable; however, many remain as static machines with only
a limited number or no changeable parameters. Electronic data loggers have replaced chart
recorders in many applications.
One of the primary benefits of using data loggers is the ability to automatically collect data on a
24-hour basis. Upon activation, data loggers are typically deployed and left unattended to
measure and record information for the duration of the monitoring period. This allows for a
comprehensive, accurate picture of the environmental conditions being monitored, such as air
temperature and relative humidity.
The cost of data loggers has been declining over the years as technology improves and costs
are reduced. Simple single channel data loggers cost as little as $25. More complicated loggers
may costs hundreds or thousands of dollars.

Machine Log Data is a file that lists actions that have occurred. For example,
Robot maintain log files listing every request made. With log file analysis
tools, it's possible to get a good idea of what and when and who command
the robot, and how they manipulate through a HMI “human-machine
interface”.

How to Convert a LOG File

If you want your LOG file to be in a different file format like CSV, PDF, or an Excel
format like XLSX, your best bet is to copy the data into a program that supports
those file formats, and then save it as a new file.

For example, you could open the LOG file with a text editor and then copy all of the
text, paste it into a spreadsheet program like Microsoft Excel or OpenOffice Calc,
and then save the file to CSV, XLSX, etc.

Converting LOG to JSON can be accomplished after you've saved it to the CSV
format. Once you've done that, use this online CSV to JSON converter.
