ICS file converter

The ICS File Converter translates common input file formats into a standards-compliant ICS calendar file. Supported inputs include CSV, TSV, XLSX, and vCard exports, as well as delimited text lists. It operates on uploaded data, automatically mapping each row into an ICS VEVENT with fields for DTSTART, DTEND, SUMMARY, LOCATION, and DESCRIPTION. The result is RFC 5545–conformant and ready for import.
Conceptually, the tool normalizes dates and times, resolves time zones, and builds recurrence rules when a recurrence field is supplied. It supports presets for typical event structures and allows custom mappings. Batch processing converts multiple rows in one run, emitting a single ICS file or multiple files depending on configuration.
Who benefits: Educators, coordinators, HR teams, freelancers, and integrators benefit from reduced manual data entry. Unique value includes strict RFC 5545 conformance, robust error handling, and flexible field mapping. Use cases include converting class schedules, employee shifts, conference agendas, and personal event lists.
