# Export Boss’nX alarms to CSV: file, columns and UTC dates

Context: Boss’nX: Alarms page of a supervision or Aggregated alarms of the hypervision, Export CSV button

The **Export CSV** button of the Boss’nX alarm history downloads the rows of the displayed tab, with your filters and sort order, into a file to open in a spreadsheet. The export is available in a supervision and in the hypervision’s aggregated alarms.

For any user authorized to view alarms: the export covers the rows accessible to them.

## Export the displayed alarms

1. Open **Alarms** in the supervision, or **Aggregated alarms** in hypervision.
2. In **Alarm History**, choose the tab you want: **Ongoing**, **Ended** or, in the supervision, **Standby**.
3. Set the search, the chips and the period bounds, then check the resulting rows. See [the history filters](https://wiki.can-nx.com/en/guides/boss-alarms-consult/).
4. Choose the order you want by clicking the header of a sortable column.
5. Click **Export CSV**, at the top right.
6. Find the file in your browser’s downloads.

The export covers the results of the active tab, with the current filters and order. The checkboxes are used for [deleting entries](https://wiki.can-nx.com/en/guides/boss-alarms-delete/): they do not define the export. To export several tabs, repeat the procedure in each one.

The file name starts with **alarms-active-**, **alarms-inactive-** or **alarms-standby-**, followed by the date and time of the export, and ends with **.csv**.

## Read the file

The file contains the columns **ID**, **Severity**, **Floor**, **Component**, **Message**, **Start**, **End**, **State**, **Triggered value**, **Cleared value** and **Acknowledged**. The values **High**, **Medium**, **Low**, **Active** and **Inactive** remain in English; acknowledgment is indicated by **Yes** or **No** in the English interface.

- **Start** and **End**: exported dates are in international UTC format, recognizable by the final **Z**, whereas the page shows the browser’s local times. In this fictional example, **2026-01-15T10:00:00.000Z** means ten o’clock UTC. A difference from the local display is therefore normal.
- **Triggered value**: the value recorded at the time of the trigger. It differs from the live value marked with a green dot in the table and does not apply that table’s presentation with unit or factor. Leave a missing value empty: it does not equal zero.
- **Project** and **Reason**: these columns are not in the file, even when the page shows them. To keep the context of an aggregated extraction, filter one project at a time and clearly identify each downloaded file.

## Open the file in a spreadsheet

If the spreadsheet asks for import options, choose the **UTF-8** encoding and the **semicolon** separator. Line breaks in texts are replaced by spaces in the file.

## Check the result

Compare the number of rows and a few values in the file with the table on the page before using the export, allowing for the UTC offset of the dates.

## Troubleshooting

- The button is disabled: the filtered list is empty, and the button may show **No alarms to export.** Check the tab, remove unnecessary filters and check the period bounds. An aggregated display hidden according to your role does not allow this export.
- No file can be found although the button is active: check the downloads and any browser prompts.

If the problem persists or if the content does not match the expected rows, contact support@can-nx.com, specifying the context, the tab, the filters and the result observed.

French labels: **Exporter en CSV**, **Aucune alarme à exporter.**, **Valeur déclenchée**, **Valeur de fin** and **Acquittée**.
