Import a CSV File

Use this guide if your weather history is already in a CSV file, spreadsheet export, or another tabular format.

Meteobreeze will read the file, map the columns you choose, convert values into canonical units, and import the selected date range into your station.

Recommended: set up your live source first, then import the CSV. That way Meteobreeze starts receiving current data right away and you avoid leaving a gap at the end of your history.

When to use it

• You exported history from another weather app
• You have a spreadsheet of observations
• You want a simple file-based import instead of a direct database connection

Before you start

• Make sure the file includes a header row
• Make sure one column contains timestamps
• Know the unit format used by each measurement column
• Know which station should receive the import

Step-by-step

1. Open the historical import flow and choose CSV.
2. Upload your CSV file.
3. Check the detected columns.
4. Map the timestamp column to observedAt.
5. Map each measurement column to the correct Meteobreeze field.
6. Set the source unit for each mapped column.
7. Set the timestamp timezone if your file uses local time.
8. Continue to the preview screen.
9. Choose the station and date range.
10. Start the import.

Common issues

• If the import will not continue, check that at least one column is mapped to observedAt.
• If values look wrong, the most likely cause is an incorrect source unit or timestamp timezone.
• If the file has blank rows or partial rows, those rows are skipped when they do not contain a valid timestamp.
• If your file has unusual headers, you may need to map them manually instead of relying on auto-detection.

FAQ

• Can I import only part of the file? Yes. Choose a custom range on the preview screen.
• Do all columns have to be mapped? No. Unmapped columns are ignored.
