Hi arcall,
Follow the steps below:
- Add a column to get the lines with only text in them (assuming based on your sample that all other lines starts with numbers)
if Value.Is(Value.FromText(Text.Start([Account],1)), type number) = true then null else [Account]
- Select the previous column and do a fill down
- Create validation column with similar formula than prior
if Value.Is(Value.FromText(Text.Start([Account],1)), type number) = true then [Category] else null
- This column as the null change with the category now filter out all the null and delete this column
- Make a split column by delimiter Space on the left most.
Check the complete M code below.
