* Wind directions might be reported as cardinal points (north, south etc) and need converting to bearings in (integer) degrees (spreadsheet packages provide ''look up'' functionality to do such conversions).
* Dates and times might need some pre-processing (spreadsheet packages usually have ability to select part of a text string and to cocatenate a number of strings) to convert them to text in the formats mentioned above. (Note - it is crucial in a spreadsheet to treat the date as text; Do not let the spreadsheet recognise it as a date as it might change the format or store as a 'days since X' number).
* Wind speed fields may not directly match to weather station outputs. See [[#Cumulus_Wind_Speed_Terminology]]
* Wind speed fields may not directly match to weather station outputs. See, for example ''EasyWeather'' differences in [[FAQ#What_do_the_various_wind_speeds_in_Cumulus_correspond_to.2C_with_Fine_Offset_stations.3F|FAQ: Wind speeds in Cumulus with Fine Offset stations]] and [[FAQ#How_do_I_set_up_recording_wind_speeds_in_Cumulus.2C_with_Oregon_Scientific_and_La_Crosse_stations| FAQ: Wind speeds with Oregon Scientific and La Crosse stations]] to pursue this; or add a post to the Support Forum for assistance.▼
* Temperature fields may not directly match to weather station outputs. Copy across the fields you can and set the others to -999.99 so they are obvious. See the [[Monthly_log_files#Using_Monthly_logs_to_deal_with_shorter_.28or_incomplete.29_dayfile.txt_records_for_particular_dates | workaround]] described below for a way of getting Cumulus to generate (from your newly created monthly logs) apparent temperature, wind chill and heat index to replace any -999.99 figures.
* Rainfall fields may not directly match to weather station outputs. [[FAQ#How_is_my_rain_rate_calculated.3F | Rain rate]] in field 8 may be generated from the [[Monthly_log_files#Using_Monthly_logs_to_deal_with_shorter_.28or_incomplete.29_dayfile.txt_records_for_particular_dates | workaround]] if unavailable from your station. The daily total in field 9 is since rollover time, and available weather station outputs may need some processing in your spreadsheet to derive this. Some stations output a count of total rainfall, others the total annual rainfall, either of these may be used for field 11. Rainfall processing issues are frequently discussed in the Support Forum, so you may find the solution there or ask there for assistance.
If you prefer to edit the start date and keep the ''recordsT.htm'' template label "Records began on" unchanged, the method is to stop Cumulus, and amend the ''StartDate='' line in [[cumulus.ini]] within the main Cumulus folder before re-starting Cumulus, but (in case you make a mistake) back up everything first!
