Data Columns to table
I have about 1200 data points for temperature, taken every hour each day. The
data is in 3 columns, date, time (0:00-24:00 hrs) and the temp reading for that hour. I want to put the data into a table with date on the left column, and the values 0:00 - 24:00 across the top. This will allow me to plot the data by day, month etc. I tried a pivot table and couldn't get the data to format the way I needed it to. Are there other suggestions for automating this task? Thanks in advance. |

Data Columns to table
Hi
(On fly) Let you have a sheet Data with a table (headers in row 1): Date, Time, Temp Add a column (p.e. RepRow) to left your table (column A now, and you can hide this column later) Define named range DataDate=OFFSET(Data!$B$1,1,,COUNT(Data!$B:$B),1) Add a sheet Periods On sheet Periods, create a table Day, Month, [Year], with according headings in row 1. Into cell Periods!A2 enter the start date. Periods!A3=IF($A$2+ROW()-2TODAY(),"",$A$2+ROW()-2) Copy Periods!A3 down as long as is reasonable for you. Periods!B2=IF(DATE(YEAR($A$2),MONTH($A$2)+ROW()-1,0)TODAY(),"",DATE(YEAR($A$2),MONTH($A$2)+ROW()-2,1)) Format Periods!B2 as "yyyy.mmmm" or "yyyy.mm", and copy also down as long as reasonable (but ~30 times less rows as column Day) When you have data for different years in same table too, then you'll need Year column too Periods!C2=IF(YEAR($A$2)+ROW()-2YEAR(TODAY()),"",YEAR($A$2)+ROW()-2) Format as General and copy down for some rows Define a couple of named ranges PeriodList=OFFSET(Periods!$A$1,,,1,COUNTA(Periods! $1:$1)) DayList=OFFSET(Periods!$A$1,1,,COUNT(Periods!$A:$A ),1) MonthList=OFFSET(Periods!$A$1,1,1,COUNT(Periods!$B :$B),1) [YearList=OFFSET(Periods!$A$1,1,2,COUNT(Periods!$C: $C),1)] Add a sheet Report. On sheet Report in row 1: Into one cell in enter "Period:", for another (it may be next one, but also further to right - it depends on width of your report columns you'll design later) apply data validation list with source "Day", "Month" [; "Year"]. Define the cell with data validation as named range Period. Further to right, for some some cell apply data validation list with source =IF(Period="Day",DayList,IF(Period="Month",MonthLi st,"")) (When you use period Year too, add an IF-level for it too) Define this cell as named range Selection On sheet Data (here the formula when you use "Day" and "Month" as periods only - when you use "Year" too, the formula will be more complex) Data!A2=IF(AND($B2<"",IF(Period="Day",$B2=Selecti on,DATE(YEAR($B2),MONTH($B2),1)=Selection),"",SUMP RODUCT(--($B$2:$B2)=Selection),--($B$2:$B2)<=IF(Period="Day",Selection,INDEX(MonthL ist,MATCH(Selection,MonthList,0)+1,))))) Copy the formula down at least for entire table. When all was right above, you'll have numbered all rows in Data table, which match with conditions estimated on Report sheet. Now you have to create a report table on sheet report - using functions ROW() to estimate report row number, and VLOOKUP(Data!$A?,...) to get according data from sheet Data. On Report sheet, you select period, and you get according report. -- Arvi Laanemets ( My real mail address: arvi.laanemets<attarkon.ee ) "Andy" wrote in message ...

Use pivot table option. drag date to the row header and time to the column
header and temp to the data zone. "Andy" wrote: I have about 1200 data points for temperature, taken every hour each day.
