ICS Merge Tool to Combine Calendar Files
Merge multiple ICS calendar files into one iCalendar file. Preview selected calendar entries, use optional date range filtering, and create a combined calendar file from local ICS data.
01. Main Features
Features of ICS Merge Tool
SysCurve ICS Merge Tool combines selected ICS calendar files into one new ICS output file for easier storage, import preparation, or review. Preview entries, use optional date range filtering, and keep every source calendar file unchanged.
Merge selected ICS files into one calendar
Combine separate calendar exports into a single ICS output file when one file is easier to store, review, or import into another calendar system.
Preview calendar records before merging
Review summaries, dates, locations, descriptions, and other available details before the merge begins. This helps confirm that the right calendar files are selected.
Use optional date range filtering
Limit the merged output to calendar entries inside a selected period. This is useful for project windows, business years, or specific archive ranges.
Add files directly or choose a folder
Select individual ICS files for a focused merge or use a folder when calendar exports are stored together in a larger collection.
Create one new output file
The merge process writes a separate ICS file in the destination folder. The original source files are not replaced.
Keep time zone information where available
The merge workflow is designed to carry useful calendar structure, including available time zone blocks, into the combined output where applicable.
Generate an optional merge log
A log can help review processed files, selected date range, merged item counts, output path, and any files that could not be processed.
Run the merge locally on Windows
The process works with saved ICS files on your computer and does not require account sign-in to the original calendar service.
More capabilities
Useful extra controls for calendar review, batch work, and output setup.
