After importing programme data, use Programme Errors to find issues and check what changed before correcting records or retrying the import.
Short answer: If you see “Import validation failed. No records saved.”, correct the named rows and import again. If the import completed with failed records, read its feedback, check which records changed and review the mappings before retrying. Then run Programme Errors to check all four tabs. Do not delete the whole programme or all attendee records as a first response.
Run the Programme Errors check
Run the check from either the dashboard or the Programme Errors page. On the dashboard, click Calculate errors in the Programme Errors widget. Or go to Core → Programme Errors. The dashboard widget does not calculate errors automatically. Opening the Programme Errors page runs the check after a brief loading animation.

Check what happened during the import
If the message says Import validation failed. No records saved., Slidecrew saved no records. Correct the rows named in the message, then import again.
If the import completed but some records failed, Slidecrew may still have saved other records. Before importing again:
- Read the feedback for the failed rows or records, and keep a copy of the spreadsheet and feedback while you investigate.
- Check which records were created or changed.
- Check the column mappings and values in the affected rows. Decide which records need correcting.
- Run Programme Errors to check for issues such as duplicate people, conflicting commitments or duration problems.
Do not delete the whole programme or all attendee records as your first response. If you cannot tell what changed, ask Slidecrew support before retrying or deleting data.
If sessions appear on the wrong dates after an import, check whether the day and month were swapped. Text dates with slashes are read month first, while text dates with dashes are read day first. Correct affected sessions before importing again: without record IDs, another import can create new sessions instead of moving the existing ones.
If sessions or presentations are missing, check the import feedback, column mappings and affected records before retrying. Check for duplicates as well as missing records.
Use the four Programme Errors tabs
The tabs group errors by the type of record. Select a subtab to see all errors for that record type or a particular issue.

|---|---|
| All | Every session error |
| No Room | Sessions not assigned to a room |
| Overlap | Sessions in the same room with overlapping times |
| Incorrect Date | Sessions dated outside the event’s configured days |
| No Presentation | Sessions with no presentations assigned |
| Time Issues | Sessions with missing or invalid start or end times |
Presentations
| Subtab | What it flags |
|---|---|
| All | Every presentation error |
| Title Errors | Presentations with missing or duplicate titles |
| No Session | Presentations not assigned to a session |
