The Scenario
The launch date slipped by two weeks. The decision was made on Tuesday. By Wednesday afternoon, the project manager has updated the roadmap doc, the calendar, and the stakeholder email. What's left: 30 Linear issues with due dates that need to shift by 14 days. The issue identifiers and new due dates are already in an Excel worksheet — the PM built it from the export they pulled last week.
The bad version:
- Open Linear, search for the first issue identifier, open the ticket, find the due date field, click it, navigate the calendar picker to the new date, save.
- Twenty-nine more to go.
- Linear's date picker requires clicking through months if the date is far out. Two months forward for a two-week shift, every time.
The PM spent the morning communicating the slip. The afternoon shouldn't be date-picker clicking.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the issue identifiers and new due dates from your worksheet and updates all of them in Linear at once.
Update the due date on each Linear issue in column A to the date in column B
What You Get
- All 30 issues updated in Linear with new due dates from column B.
- Rows where column B is blank are skipped rather than having their due date cleared.
- Identifiers that don't exist surface as warnings.
- A completion summary with the count updated and any failures.
What If the Data Is Not Quite Ready
Only reschedule rows explicitly marked for it
Set the due date to the value in column C for every Linear issue identifier in column A where column B says "reschedule"
Calculate new dates from existing ones
For each Linear issue identifier in column A: get the current due date, add 14 days, and set the new due date — write the original and new date into columns B and C
Clear due dates where column B says "none"
For each Linear issue in column A: if column B contains a date, set that as the due date; if column B says "none", remove the due date entirely
Full reschedule with validation and writeback
For each row in this workbook where column B says "reschedule": update the Linear issue in column A to the due date in column C — write "updated" into column D if it succeeded, the error message if it failed, and flag "was overdue" in column E if the original due date was before today
Try It
Get the 7-day free trial of SheetXAI and open any Excel workbook with Linear issue identifiers and revised due dates — then ask it to apply all the date changes at once. If this slip also requires updating milestone target dates at the project level, the create-project-and-milestones guide covers that.
