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.

ICS is parsed into rows and columns first. These settings control that extracted table and how the output CSV is written—not the source file syntax.
Each row is an iCalendar property found in your VEVENT data.
Edit Mapping to set the column title in the exported csv 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).
CSV field delimiter is set under Conversion options above.

Map each VCF field to a normalized table column. Use Include to choose output lines.
| # | VCF Field | Mapping | Include |

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

Overview & guides
Easily convert iCalendar files into CSV with the iCalendar to CSV Converter, ideal for spreadsheet tasks.
Perfect for tabular data processing, this converter guarantees secure and accurate conversions, simplifying data handling for all users.
You can either paste your iCalendar data directly into the input field or upload a file. Use Load Sample to try the sample calendar, map properties to columns, and choose CSV as the output format.
Once the CSV output is ready, you can copy it using the copy icon or save it as a file by specifying a file name.
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 CSV output.
Step 3: Include Desired Properties:
In the mapping section, include or exclude specific iCalendar properties to tailor the CSV output according to your requirements. You can also set the field separator for CSV.
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: Copy or Download CSV:
Upon completion, the CSV appears in the output area; copy it or download the file (optional custom file name).
Step 6: Date / time standard on export:
ICS date-time fields are written as fixed ISO-like text (see the ICS → XLSX guide for the full pattern list). EXDATE / RDATE use comma-separated tokens in the same style.
Step 7: Round-trips:
If you edit the CSV elsewhere and convert back to ICS, keep the same date/time text forms or re-import through Excel using real Date/Time cells—avoid ambiguous locale-only strings.
1. What is iCalendar (ICS) to CSV conversion on ConversionTab?
iCalendar (ICS) to CSV conversion on ConversionTab allows you to convert iCalendar files or iCalendar text strings into CSV (Comma-Separated Values) 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 conversion?
After conversion, you can customize the CSV output with the following options:
- Mapping: Modify column names as needed.
- Include: Select or deselect columns for the final CSV output.
- Field Separator: Choose the separator character for CSV fields (e.g., comma, semicolon).
7. Can I specify which iCalendar properties to include in the CSV output?
Yes, you can select or deselect specific iCalendar properties to include in the final CSV output based on your requirements.
8. Is there an option to handle recurring events during conversion?
Yes, ConversionTab provides options to handle recurring events during conversion, allowing you to specify how recurring events should be represented in the CSV output.
9. How are dates and times formatted in the CSV export?
The same fixed ISO-like standard applies as for ICS → Excel (UTC with Z, offsets, date-only, floating local times; comma-separated EXDATE/RDATE tokens). Per-column custom format strings are not offered—match this shape if you edit the CSV and convert back to ICS.
10. Is there an option to preview the CSV output before conversion?
Yes, you can preview a sample of the CSV output to ensure that the conversion results meet your expectations before proceeding with the conversion.
11. How do I get the CSV output?
Once the mapping and settings are complete, users can initiate the conversion process by clicking the 'Convert' button. The resulting CSV data is displayed in a textarea, providing users with two options:
- Copy: Users can copy the generated CSV data for use elsewhere.
- Download: Users can download the CSV file, with the option to specify a custom file name if desired.
This flexibility ensures that users can choose the most suitable method for accessing their converted data.
12. 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.
13. How can I clear the output and start over?
