How to Import 100,000 Excel Rows into a SharePoint List

Question details

The user needs to import a massive dataset of 100,000 rows from an Excel spreadsheet into a SharePoint list but faces platform constraints when using standard methods like Power Automate or Microsoft Lists.

Product: SharePoint / Microsoft Excel
Device & OS: not provided
Scenario: Attempting to bulk import a highly populated Excel dataset into a SharePoint list structure.
Observed behavior: Standard user interface imports and Power Automate workflows struggle, time out, or fail due to the volume of data, and SharePoint's native 5,000-item view threshold limits list usability after import.

Before you start

Evaluate whether a SharePoint list is the most appropriate storage solution for this data volume, as SharePoint enforces a strict 5,000-item view limit that can significantly degrade list performance and usability with 100,000 rows.

Solution 1Recommended

Use PowerShell Scripts for Bulk Data Import

Bypass the standard UI limitations of Microsoft Lists by using a PowerShell script to chunk and upload large datasets programmatically.

Standard Microsoft Lists features and Power Automate often time out or hit API thresholds when processing 100,000 rows. PnP PowerShell provides a robust backend method to chunk data and push it sequentially into SharePoint without relying on browser stability.

Convert Excel to CSV

Open your Excel spreadsheet and save the file as a CSV (Comma Delimited) format. This makes the data lighter and easier for a script to parse.

Install PnP PowerShell

Open Windows PowerShell as an administrator and execute 'Install-Module -Name PnP.PowerShell' to install the required SharePoint interaction tools.

Connect to SharePoint Site

Run the command 'Connect-PnPOnline -Url https://yourdomain.sharepoint.com/sites/yoursite -Interactive' and log in with your administrative credentials.

Execute Batch Import

Write and run a script utilizing 'Import-Csv' and 'Add-PnPListItem' inside a loop to iterate through the CSV file and write the data directly to your target SharePoint list.

Solution 2

Import via Microsoft Access Database Connection

Link your SharePoint list to a Microsoft Access database to leverage a more robust engine for uploading massive Excel tables.

Frequently Asked Questions

What is the SharePoint 5,000-item view threshold?

The 5,000-item view threshold is a database performance safeguard in SharePoint. It prevents a single SQL query from returning more than 5,000 items simultaneously. While a list can physically store up to 30 million items, you cannot view, sort, or bulk-edit more than 5,000 at a time unless you set up indexed columns and heavily filtered views.

Can I use Power Automate to import 100,000 Excel rows?

While technically possible, using Power Automate to loop through 100,000 rows is highly discouraged. The flow will likely encounter severe throttling, API call limits, and execution timeouts. A dedicated scripting tool like PowerShell is much more appropriate for bulk migrations.

What is the best alternative to SharePoint lists for massive datasets?

For structured datasets exceeding 100,000 rows, consider utilizing Microsoft Dataverse, an Azure SQL Database, or simply keeping the data in robust Excel / WPS Spreadsheet files stored securely inside a SharePoint Document Library instead of forcing it into a SharePoint List.
