ICS Duplicate Remover Tool to Clean Repeated Calendar Events

Find and remove duplicate calendar entries from ICS files using selectable match criteria. Preview calendar items, clean duplicates within each file or across selected files, and create CSV or HTML reports locally.


Features of ICS Duplicate Remover Tool

SysCurve ICS Duplicate Remover Tool reduces repeated calendar entries from local ICS files using selected match rules. Preview calendar data, choose within-file or across-file cleanup, and create cleaned ICS output with practical reports.


Remove duplicates within each ICS file

Clean repeated entries inside individual calendar files when duplication exists in the same export. This is useful after repeated exports or calendar sync issues.

Find duplicates across selected files

Compare selected ICS files together when the same calendar item appears in more than one export. This helps reduce overlap before merge, archive, or import work.

Choose match criteria for better control

Select fields such as UID, summary, start time, and location instead of relying on one fixed duplicate rule. Different calendar sources may store repeated events in different ways.

Use normalization options when needed

Options for case handling and date/time normalization help with minor formatting differences in calendar exports.

Preview calendar entries before cleanup

Review selected calendar data before starting duplicate removal. This makes it easier to confirm the correct files and cleanup scope.

Create cleaned ICS output files

The software writes cleaned calendar copies to the destination folder while leaving original ICS files unchanged.

Generate CSV and HTML reports

Reports can show duplicate groups, kept items, removed duplicates, source files, and output details after processing.

Work locally on Windows

Duplicate removal runs on your computer and does not require uploading calendar data or signing in to a calendar account.
