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.

Max 25 MB. Loads into the same editor as the Text tab; use Convert below.

Each row is an iCalendar property found in your VEVENT data. Edit Mapping to set the column title in the exported xlsx output; use Include to omit properties.

Date/time columns use the ConversionTab standard described above the conversion options (ISO-like UTC/offset/local forms, or Excel Date cells when you build the sheet yourself).

# ICS value Mapping Include
Provide valid iCalendar above to load output options.

Map each VCF field to a normalized table column. Use Include to choose output lines; Check all / Uncheck all sit under the mapping table.

# VCF Field Mapping Include
Provide input above to load mapping options.

Column names and types feed SQL generation (same rules as the CSV tool).

# Field Name Data Type Max Size Key Include Trim NULL empty

What this conversion is for

Use it when the next reviewer or pipeline step insists on Excel XLSX, not raw iCalendar. You get a workbook with typed cells for finance-style review and pivots.

From iCalendar to Excel XLSX in four moves

Paste iCalendar text or upload the calendar/contact file.

Scan VEVENT blocks, DTSTART/DTEND, and UID lines for obvious duplicates.

Use mapping or options on this page so each iCalendar field lands in the correct Excel XLSX shape.

Download .xlsx for reviewers who need filters, types, and comments.

Before you convert

  • Recurrence (RRULE) and timezone rules may simplify when flattened.
  • Very wide sheets may feel sluggish—trim columns when possible.
  • Keep a copy of the original iCalendar as the audit trail after you ship Excel XLSX.

Choose the right output

When Excel XLSX is the right output

  • You are promoting iCalendar into Excel XLSX because the next hop names that format in its contract or runbook.
  • Downstream asked explicitly for Excel XLSX while editors still live in iCalendar.
  • You need a deterministic export for CI, legal, or partner review—not a live sync.
  • The receiving system has a documented Excel XLSX ingest path (template, parser, or app import).

When another format fits better

  • GitOps and CLI diff prefer CSV/YAML/JSON text over binary workbooks.
  • Server-side ingestion often wants CSV or SQL, not XLSX parsing in production.
  • Lightweight mobile review may prefer PDF screenshots over full Excel.
  • When only a few columns matter, CSV is smaller and faster to transfer.

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.

Input format notes

About iCalendar as the source

iCalendar is parsed as structured input for this page. Use complete rows, valid syntax, and consistent field names so the converter can preserve the important data when creating Excel XLSX.

Output format notes

About Excel XLSX as the output

Excel XLSX is generated from the parsed iCalendar data. Review the output before importing it into another system, especially when the destination expects strict columns, dates, or contact fields.

Conversion guide

How to Convert ICS to XLSX?

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.

Questions before converting

ICS (iCalendar) to XLSX Conversion FAQs

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:
