Create Splunk dashboard with data from excel file

1. Can Saved Searches Update an Excel File with Predefined Columns?

Not directly. Splunk saved searches export results in formats like:

CSV

JSON

XML

But you can:

Schedule a saved search to export as a CSV.

Use a script (Python, PowerShell, etc.) outside of Splunk to:

Watch the exported file.

Insert data into a predefined Excel template.

Save it as .xlsx.

Example:

Use the outputcsv command in your saved search:

your search query

| outputcsv my_output.csv

Then use Python (with pandas and openpyxl) to map this CSV into a predefined Excel template.

2. Can You Use Excel Files to Create Splunk Dashboards?

No, not directly. Splunk dashboards rely on:

Indexed data in Splunk

Real-time or scheduled searches

Lookups (CSV-based), not .xlsx

But you can:

Convert your Excel file to CSV

Upload it as a lookup table in Splunk

Use it in searches like:

| inputlookup my_excel_data.csv

From there, you can create dashboards.
