Conversions run in your browser; structured data is flattened to a table when needed, then the same engines as /csv/* are applied.
ConversionTab date / time standard (ICS → table)
Calendar fields such as DTSTART, DTEND, DTSTAMP, CREATED, and LAST-MODIFIED are exported as ISO-like text (not raw Excel serials): for example 1997-07-14T17:00:00Z for UTC, 1997-07-14T17:00:00+05:30 for a fixed offset, 1997-07-14 for all-day style dates, or 1997-07-14T17:00:00 when the ICS value has no Z / zone. EXDATE / RDATE lists use commas between values in the same style.
If you edit the file elsewhere and later convert back to ICS (e.g. from Excel), use these same shapes in cells—or real Excel Date/Time cells—so start/end and timestamps map reliably. Locale-only strings (e.g. 14/07/1997 alone) are not guaranteed to parse.

Overview & guides
Easily convert iCalendar files into Excel with the iCalendar to Excel Converter, ideal for Excel spreadsheets.
Designed for data analysis, it offers secure and accurate conversions, making professional reporting transformations effortless.
You can either paste your iCalendar data directly into the input field or upload a file. Use Load Sample for the ready-made sample calendar, choose Excel as the output format, and your converted file will be ready shortly.
Your converted Excel file is ready to download. Save it to your device for immediate use.
Step 1: Input iCalendar Data:
Start by providing your iCalendar data either by manually inputting it as a valid string in the designated tab or by uploading an ICS file through the 'Drop/Browse File' feature. You can also click Load Sample to load a sample calendar (Project XYZ meeting with EXDATE, RDATE, GEO, and more).
Step 2: Mapping Columns:
Before initiating the conversion process, navigate to the mapping section. Here, you can customize how iCalendar properties are mapped to columns in the final XLSX output.
Step 3: Include Desired Properties:
In the mapping section, include or exclude specific iCalendar properties to tailor the XLSX output according to your requirements.
Step 4: Proceed with Conversion:
Once you've mapped the columns and included the desired properties, proceed with initiating the conversion process by clicking the 'Convert' button.
Step 5: Direct Download:
Upon completion of the conversion process, ConversionTab will generate the XLSX file according to the mapping options you've selected. The resulting XLSX data will be available for direct download.
Step 6: Date / time standard on export:
ICS date-time fields (for example DTSTART, DTEND, CREATED, LAST-MODIFIED) are written as fixed ISO-like text: YYYY-MM-DD for date-only, YYYY-MM-DDTHH:mm:ssZ for UTC, YYYY-MM-DDTHH:mm:ss±HH:MM for fixed offsets, or YYYY-MM-DDTHH:mm:ss when the source used a floating local time. EXDATE / RDATE keep comma-separated tokens in the same style.
Step 7: Editing outside ConversionTab:
If you change the workbook elsewhere and later use Excel → ICS here, keep those same text shapes or use Excel’s real Date/Time cells—avoid locale-only strings such as 14/07/1997 alone. You cannot pick a custom display format inside the tool; the export above is the supported contract.
1. What is iCalendar (ICS) to XLSX conversion on ConversionTab?
iCalendar (ICS) to XLSX conversion on ConversionTab allows you to convert iCalendar files or iCalendar text strings into XLSX (Excel Spreadsheet) format.
2. How do I provide my iCalendar data for conversion?
You can input your iCalendar data in two ways:
- Text: Users can manually input ICS data as a valid string in this tab.
- File Tab: Users can upload their ICS file through the 'Drop/Browse File' feature, simplifying the process of working with existing data.
3. Which iCalendar versions are supported for conversion?
ConversionTab supports a range of iCalendar versions, including iCalendar 2.0, for conversion.
4. How do I initiate the conversion process?
After entering your iCalendar data or selecting a file, click the 'Convert' button to start the conversion process.
5. What happens if my provided data is not a valid iCalendar file or string?
If your input data is not a valid iCalendar file or string, ConversionTab will display an error message, and the conversion will not proceed.
6. What controls are available after mapping and before conversion?
After mapping your data, you can customize the XLSX output with the following options:
- Mapping: Modify column names as needed.
- Include: Select or deselect columns for the final XLSX output.
7. Can I specify which iCalendar properties to include in the XLSX output?
Yes, you can select or deselect specific iCalendar properties to include in the final XLSX output based on your requirements.
8. How are dates and times formatted in the XLSX export?
ConversionTab uses a fixed ISO-like standard for calendar fields (for example 1997-07-14T17:00:00Z for UTC, 1997-07-14 for date-only, ±HH:MM offsets when present in the ICS, or local T times without Z for floating date-times). You cannot choose a different display mask in the UI—this export is the documented contract for round-trips.
9. How do I get the XLSX output?
Once the mapping and settings are complete, users can initiate the conversion process by clicking the 'Convert' button. The resulting XLSX data can be downloaded directly.
10. Is there sample iCalendar data, and how do I clear the editor?
ConversionTab offers additional features to improve the user experience:
- Load Sample: Click Load Sample to load the sample calendar (Project XYZ meeting with EXDATE, RDATE, GEO, and more).
- Clear: Use Clear to reset input and output when you want a clean slate.
