iCalendar to CSV

Online iCalendar to CSV Converter

Convert ICS/iCalendar to CSV with column mapping and Include controls—paste text, upload a file, or use Load Sample. Ideal for calendar analysis and spreadsheet tools.

The layout highlights validation and preview steps so CSV output keeps the important structure from iCalendar.

Conversion focus

Private by design: iCalendar content is processed locally in the browser.

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 file

Drop a file here, or click to browse

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

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.

Output CSV delimiter

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.

# 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.
Include column:

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

# Field Name Data Type Max Size Key Include Trim NULL empty
Provide input to load columns.

What this conversion is for

Treat this as a one-way export: validate structure in iCalendar, then accept CSV semantics on the other side. You get delimiter-separated rows ideal for Excel, data lakes, or quick diffs in Git.

From iCalendar to CSV 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 CSV shape.

Convert, then copy or download UTF-8 CSV for spreadsheets or pipelines.

Before you convert

  • Recurrence (RRULE) and timezone rules may simplify when flattened.
  • CSV loses rich typing—dates become text unless the next tool re-coerces.
  • Keep a copy of the original iCalendar as the audit trail after you ship CSV.

Choose the right output

When CSV is the right output

  • You are promoting iCalendar into CSV because the next hop names that format in its contract or runbook.
  • Downstream asked explicitly for CSV 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 CSV ingest path (template, parser, or app import).

When another format fits better

  • Programs expect nested objects or arrays—use JSON or XML instead of flattening too early.
  • You need executable INSERT/MERGE with keys—generate SQL rather than stopping at CSV.
  • Recipients want typed Excel features immediately—ship XLSX, not plain CSV.
  • Always-on replication belongs in APIs or streams, not repeated manual CSV drops.
Suggested workflow
  1. Paste iCalendar content or upload a compatible file.
  2. Review detected columns, mappings, and optional limits before conversion.
  3. Convert to CSV, preview when the page supports it, then download the result.

iCalendar to CSV overview

iCalendar to CSV Converter Overview

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.

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 CSV.

Output format notes

About CSV as the output

CSV 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 CSV?

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.
