Source Your Data Files
Source your data. Spell out exactly where it came from, so that someone other than you, several years in the future, could understand its origin.
Label the file name
Everyone has seen examples of bad file names:
Write a short but meaningful file name. It is a good idea to include data source in file name (eg
eurostat). If different versions of the data are floating around, add the current date at the end, in YYYY-MM-DD format. Good file names look like this:
Save source data in separate sheet
Before modifying the original dataset, make sure to duplicate it to avoid any data losses. One way is to click (or right-click) on the spreadsheet tab to copy the sheet to another tab as a backup.
Add a source tab, after the data, with notes to remind you and others about its origins and when it was last updated.
