Introduction
Exporting data from dsquery to CSV can be a crucial task for system administrators and data analysts. This guide will walk you through the steps necessary to perform this export process efficiently and accurately.
Dsquery, a command-line tool in Windows, is used to query Active Directory for various types of data. The output can be redirected into a CSV file for easy handling and further analysis.
You'll also learn how Sourcetable lets you analyze your exported data with AI in a simple to use spreadsheet.
Exporting Data to CSV Format Using dsquery
- Dsquery is a command-line tool used to query Active Directory. Although dsquery does not output data directly in CSV format, it can be combined with other commands or methods to achieve this. This guide will detail the processes required to export dsquery data to CSV format.
- To export a list of users from Active Directory to a CSV file, you can combine dsquery with dsget. This combination allows dsquery to query user information, and dsget to format the output. The command is as follows:
- dsquery user dc=contoso,dc=com | dsget user -samid -fn -ln -dn > names.csv
- This command queries all user objects within the specified domain and exports the samid, fn, ln, and dn attributes to names.csv.
- An alternative and more straightforward method to export dsquery results is using the csvde command. Csvde is designed to export data directly to CSV format, eliminating the need for additional conversion steps. The csvde command for exporting users is:
- csvde -f names.csv -r "(&(objectClass=user)(objectCategory=user))" -l samAccountName,givenName,sn
- This command specifies the output file as names.csv and filters the query to include only user objects. It exports the samAccountName, givenName, and sn attributes.
- Another method to export dsquery results to a CSV file involves using PowerShell. While this method requires more steps, it can be more flexible. The following PowerShell script can be used:
- [adsisearcher]'(&(objectClass=user)(objectCategory=user))'<br/>$a.PageSize = 1000<br/>$a.PropertiesToLoad.AddRange(@('samAccountName', 'givenName', 'sn', 'distinguishedName'))<br/>$a.FindAll() | ForEach-Object {
- $_.Properties.samAccountName, $_.Properties.givenName, $_.Properties.sn | Export-Csv -Path names.csv -NoTypeInformation
- This script queries Active Directory for user objects and exports the samAccountName, givenName, and sn attributes to a CSV file named names.csv.
- While dsquery combined with dsget provides a quick way to export data, it outputs results as a space-separated list, which may require additional formatting for true CSV. Csvde is preferred for direct CSV export as it simplifies the process and outputs in the required format. PowerShell offers greater flexibility and control over the output but involves more complex scripting.
- Using any of these methods allows for the effective extraction and conversion of Active Directory user information to CSV format, catering to various requirements and preferences within IT environments.

How to Export Data to CSV Format Using dsquery
Introduction
Exporting user data to CSV format from your domain can be efficiently achieved using dsquery and csvde commands. This guide will walk you through the process to ensure you capture the relevant attributes of your users.
Why Use csvde Instead of dsquery
While dsquery can be used to list users, it does not natively support CSV output. The csvde command is recommended as it directly exports data to CSV, ensuring a more reliable and correctly formatted output.
Exporting User Data with csvde
To export user data to a CSV file using csvde, use the following command:
csvde -f names.csv -r "(&(objectClass=user)(objectCategory=user))" -l samAccountName,givenName,sn
This command will create a CSV file named names.csv, including the attributes samAccountName, givenName, and sn.
Understanding the csvde Command
The -f flag specifies the output file for the CSV data. The -r flag allows you to define a query to filter the objects being exported, where "(&(objectClass=user)(objectCategory=user))" filters for user objects. The -l flag lists the attributes to be included in the export.
Limitations of dsquery
Using dsquery requires the dsget command for formatting, and the output is space-separated rather than true CSV. Additionally, dsquery outputs only 100 objects by default unless modified with the -limit 0 option. To avoid these complications, it is recommended to use csvde for exporting to CSV.
Example Commands
Example of using dsquery and dsget with PowerShell for partial CSV formatting:
dsquery user dc=contoso,dc=com | dsget user -samid -fn -ln -dn > names.csv
While this command outputs a space-separated list, it does not produce a true CSV. For reliable CSV exports, use the csvde command as shown above.
Conclusion
For exporting user data to CSV format, leverage the csvde command for a reliable and correctly formatted output. Avoid using dsquery alone due to its limitation in producing a true CSV format.

Use Cases for dsquery
Situational Awareness in Active Directory |
Dsquery can be leveraged for offensive AD situational awareness. By enumerating users, computers, and groups, administrators and penetration testers can gain an understanding of the Active Directory environment. This can be pivotal for identifying weak points and potential entry vectors. |
User and Group Enumeration |
Dsquery is instrumental in enumerating users and groups within Active Directory. Queries can be executed to find users with specific attributes or identifiers, such as those that include "admin" or "password" in their descriptions. Additionally, dsquery can identify users belonging to multiple groups, aiding in the creation of security assessments. |
Inactive and Disabled Account Identification |
Using dsquery, administrators can easily find inactive or disabled accounts. For example, running the command `dsquery user -inactive 5` can output a list of users who have not been active in the last five weeks, helping streamline account cleanup processes and enhance security. |
Target-Specific Computer Searches |
Dsquery allows for the identification of specific computers or groups of computers within a domain. This is useful in larger environments where locating machines with certain criteria is necessary for management, maintenance, or security assessments. |
Advanced LDAP Queries |
Dsquery supports advanced LDAP queries, enabling detailed searches within the directory. For example, `dsquery * -filter "(&(objectclass=user)(!(objectclass=computer)(name=*W*)))"` looks for users whose names contain the letter "W", excluding computer objects. This capability enhances the flexibility and power of directory searches. |
Automation and Piping with Other Tools |
Results from dsquery commands can be piped as input to other directory service command-line tools like Dsget, Dsmod, Dsmove, or Dsrm. This allows for streamlined workflows and automation of directory management tasks, making dsquery a versatile tool in Active Directory environments. |
Cross-Domain Querying |
Dsquery is capable of querying across domains by specifying the server to query by FQDN or IP address. This feature is invaluable in complex environments with multiple domains, helping to manage and secure the entire AD infrastructure holistically. |
Finding Last Login Information |
Dsquery can be used to find out when a user or users last logged into the domain. This information is crucial for monitoring user activity and identifying potentially compromised accounts that might not replicate last login details across domain controllers. |
