/*
This is not a script, but a configuration for the Expensify custom export template.
In the export format editor, create a new column for each line below, using the text on the right as the formula.
*/

// Case ID and Required Attributes
ExpenseReportId: {report:id}
EventTime_Created: {report:created}
EventTime_Submitted: {report:submitted}
EventTime_Approved: {report:approved}
EventTime_Reimbursed: {report:reimbursed}
EventTime_Closed: {report:closed}

// Recommended Attributes
ReportTotalAmount: {report:total}
Submitter: {report:submitter:email}
Approver: {report:approverEmail}
EmployeeDepartment: {report:tag:[Your Department Tag Name]}
PolicyViolationFlag: {report:hasViolations}

// --- Transformation Logic Overview ---
/*
After exporting the CSV with the columns above, you must unpivot the timestamp columns.
1. Load the CSV into a data transformation tool (e.g., Excel Power Query, Python pandas).
2. Select all the timestamp columns (EventTime_Created, EventTime_Submitted, etc.).
3. Use the "Unpivot" function. This will create two new columns: one containing the original column names (e.g., 'EventTime_Created') and another with the timestamp values.
4. Rename the column with the names to `ActivityName` and the column with values to `EventTime`.
5. Clean up the `ActivityName` column by removing the 'EventTime_' prefix to get clean activity names like 'Expense Report Created', 'Expense Report Submitted', etc.
6. For activities that do not have a direct timestamp export (e.g., 'Manager Approved', 'Reimbursement Scheduled'), you can duplicate an existing timestamp column (like 'EventTime_Approved') in your export template and rename it accordingly (e.g., `EventTime_ManagerApproved`). This uses the same timestamp as a proxy for multiple events, which should be noted during analysis.
