Today you will

• add a dated change log to {{code:05_project_budget}}
• save an editable copy and a PDF of your budget
• bring back an earlier version with version history

Key Assignment: your two saved copies can count as evidence.

If you don't have a budget file yet, tell your teacher.

Warm-up

Think of the last file you sent someone. Did they need to change the numbers, or only read them?

An editable workbook is the live spreadsheet you keep changing as your plans change.

A PDF is a fixed snapshot that is hard to change by accident.

Version history keeps earlier saves of a cloud file so you can bring one back.

A change log is a short dated note at the top of your sheet that says what changed.

You will add a change log to your budget. Then you will save an editable copy and a PDF into {{code:05_budget}}.

Watch your teacher first, then follow the steps in the box below. A file left in Downloads does not count, so always upload it to {{code:05_budget}}.

You will make a test edit on purpose, then bring back an earlier version. Follow the steps in the box below.

After the test edit, wait until your file says it is saved before you open the history. Your teacher will count to ten with you.

Common issues

• Version history is empty. Wait until your file says it is saved, then refresh the page and open history again.
• My copies are only in Downloads. Rename them and upload both into {{code:05_budget}}.
• Google Sheets opened a print panel. That is normal. Click {{btn:Export}} or {{btn:Download}} to finish the PDF.
