About this global bulk CSV calendar converter
This tool is for anyone working across calendars—not only Afghan contexts. Researchers, journalists, NGOs, genealogists, and product teams worldwide use it to normalize dates in bulk. You upload or paste a UTF-8 CSV where each row marks the source as Miladi (international civil calendar) or Shamsi (solar Hijri months, aligned with common Persian and Afghan calendar practice). The server returns Miladi, Shamsi, and approximate Islamic Hijri so you can merge international datasets, migration records, and regional archives without manual re-entry.
Why use a bulk converter instead of single-date tools?
Single-date converters are ideal for quick checks. When you have dozens or thousands of rows—civil registration, logistics, historical corpora, or CRM exports—a batch CSV path cuts errors and timezones of confusion. The logic matches the main Afghan Date Converter on this site, so results stay consistent for teams in Kabul, London, Dubai, Toronto, or anywhere else.
International search phrases this page supports
People often discover this workflow using terms such as:
- Bulk Miladi to solar Hijri (Jalali / Shamsi) CSV for research or media
- Spreadsheet export: Western dates ↔ solar Hijri months for global reporting
- Batch Islamic Hijri approximation next to civil and solar-Hijri columns
- Free online cross-calendar converter—no account, UTF-8 CSV worldwide
Keep a backup of your source file. If a row is invalid (for example, a non-existent solar-Hijri day), you will see the CSV line number and a short reason—fix the row and convert again. Download the enriched CSV and continue in Excel, Google Sheets, Numbers, or any UTF-8-friendly database.
