Also called CSV.

Terms in this definition
- General-purpose v1
The older storage account kind (
Storage), which lacks access tiers, Archive and premium file shares and retires on 13 October 2026. Converting to ZRS requires first upgrading to GPv2, a one-way change. - ALL
A DAX function that ignores any filters and gives back every row of a table or every value of the named columns. Used within CALCULATE, it works as a modifier that clears filters, although REMOVEFILTERS states that intent more clearly where it is available.
- Scale-Out File Server
A failover cluster role in which every node serves the same SMB shares simultaneously, intended for application workloads like SQL Server database files and Hyper-V virtual machines.
- Hyper-V
The hypervisor built into Windows. The VMs for the Azure Extended Network appliance require the Hyper-V role, using nested virtualisation, and an external virtual switch for each NIC.
Related terms
- API-driven inbound provisioning
Inbound Microsoft Entra provisioning in which an app or script submits SCIM bulk requests built from any HR source, a CSV file for instance. The ECMA connector, by contrast, provisions outbound.
- ASCII
An encoding for human-readable files like JSON or CSV that turns their bytes into printable characters. Unicode supports far more characters.
- AuditData
When audit search results are exported to CSV, this field carries the full detail of every record as JSON. Excel's Power Query can expand that JSON into individual columns.
- Autopilot diagnostics page
If the Enrollment Status Page profile allows it, pressing Ctrl+Shift+D during Windows 11 OOBE opens this page. It shows what the deployment is doing and can export logs, one of which is a CSV with the hardware hash.
- Bulk operations
Entra admin centre tasks run from a CSV template you download first: creating member users, inviting guests, deleting users (only the UserPrincipalName column) and exporting the user list.
- CETAS
Writes the result of a query out to external storage as files (CSV or Parquet, say), in parallel, and creates an external table over them, all in one T-SQL statement.
- Corporate identifiers
Lists you upload to Intune so devices are recognised as corporate-owned when they enrol: IMEI or serial numbers, or for Windows the manufacturer, model and serial. Each CSV may hold 5,000 rows or 5 MB at most.
- Delimited text
Plain text where a chosen separator character divides fields and a terminator closes every row; CSV, TSV and fixed-width files are common forms. Good for structured data that many programs need to read.
