How to Fix Microsoft Teams Shifts Excel Import Errors

Preserve the current team template

Download the Shifts template for your team and keep the original. Upload a standard XLSX workbook or paste supported schedule CSV rows. Select the actual source date order.

The checker uses a 10 MB safety limit. Formula cells and unsupported workbook structures are rejected. It does not calculate spreadsheet formulas or invent missing member details.

Read the original schedule report

Review worksheet columns, required values, durations and the local timeline. Shifts and open shifts over 24 hours are unsupported, while multi-day time off is allowed.

The report checks per-entity and total workbook limits. It cannot verify live team membership, group permissions or whether these records duplicate an existing imported schedule.

Make only approved schedule changes

Sample removal, overnight end-date changes and long-field truncation are separate unchecked options. Select them only when they match the approved roster.

A 26-hour shift needs a source decision. An overnight time does not prove the intended date. Correct regional-date mismatches and missing values from the schedule owner rather than changing them merely to pass.

Inspect a revalidated workbook

The tool checks a candidate again before its download appears. Unknown or changed columns block export so their contents are not silently discarded. The audit remains available when a workbook cannot be downloaded.

Compare the output sheets, dates, names and durations with the original. Import through Shifts and inspect its import history and error report. Passing local checks does not establish successful import.
