Are you a ServiceNow user needing to extract an entire table – every single record and every field, including system fields like sys_id – into a manageable Excel or CSV file? While ServiceNow offers various export options, getting a complete data dump can sometimes feel tricky. This article provides a straightforward method to export all data and fields from a ServiceNow table, addressing a common challenge faced by developers and admins who need comprehensive data for analysis, migration, or reporting purposes. We'll guide you through the process step-by-step, enabling you to quickly obtain the complete data you need from your ServiceNow instance.

The Challenge: Exporting Everything

ServiceNow's built-in export functionalities are often geared towards exporting data from a list view or a report. This is very helpful, but these approaches might not include every field in a table, especially system-related columns that aren't typically displayed in list views. When you need a complete picture of your data, including those hidden fields, you need a different approach.

The Solution: Leveraging the sysparm_default_export_fields=all Parameter

The key to exporting all data and all fields lies in using a specific URL parameter: sysparm_default_export_fields=all. This parameter instructs the ServiceNow web service to include every field in the table in the export, including the all-important sys_id and other system-managed fields.

Here's how to use it:

  1. Navigate to the Target Table: In your ServiceNow instance, go to the list view of the table you want to export. For example, if you want to export all incidents, navigate to incident_list.do.
  2. Apply Filters (Optional): If you only want to export a subset of the records, apply the necessary filters using the list view's filter functionality. For instance, you might filter for only active incidents (sysparm_query=active=true).
  3. Craft the Export URL: This is the crucial step. Take the URL from the address bar and modify it by adding the following to the end:&CSV&sysparm_default_export_fields=allFor example, if your incident list URL with the "active" filter is:https://<your-instance>.service-now.com/incident_list.do?sysparm_query=active=trueThe modified URL for exporting all fields would be:https://<your-instance>.service-now.com/incident_list.do?sysparm_query=active=true&CSV&sysparm_default_export_fields=all
  4. Execute the URL: Paste the complete, modified URL into a new browser window or tab and press Enter.
  5. Download the CSV File: ServiceNow will automatically generate and download a CSV file containing all records and all fields from the table, including sys_id.

Important Considerations

  • Performance Impact: Exporting a large table with many fields can potentially impact your instance's performance, especially during peak hours. Consider performing these exports during off-peak times if you're dealing with a very large dataset.
  • Data Size Limits: Be mindful of potential data size limitations when exporting to CSV. Excel has limitations on the number of rows it can handle. If you're exporting a massive table, consider alternative formats or methods for handling the data.
  • Security: Be cautious about who has access to these exported files, as they contain the complete data from your ServiceNow table. Ensure appropriate security measures are in place to protect sensitive information.
  • Alternative Solution: For very large datasets, consider using ServiceNow's built-in data export capabilities with a scheduled job to export data in smaller chunks or explore using the ServiceNow API for more controlled and scalable data extraction.

Exporting all data and fields from a ServiceNow table doesn't have to be a daunting task. By leveraging the sysparm_default_export_fields=all parameter, you can quickly obtain a comprehensive CSV file containing every record and every field, including system fields. Remember to consider performance implications and data security when working with large exports.
