Question details

The user needs a way to add or correct text prefixes across multiple SharePoint list items while preserving the existing unique data stored in each cell.

How to Bulk Edit SharePoint List Values Without Losing Unique Data

Product: SharePoint
Device & OS: not provided
Scenario: Standardizing asset tags or reference numbers in a large SharePoint list by updating prefixes (like SL or SL21) without manually rewriting every single entry.
Observed behavior: SharePoint's native bulk editing replaces the entire cell value, preventing users from modifying only a specific part of a text string.

Before you start

Ensure you have the appropriate permissions to export lists from SharePoint and verify that your target column is not set to read-only.

Solution 1Recommended

Export to a Spreadsheet and Calculate Values with a Helper Column

By exporting your SharePoint list to a spreadsheet program, you can use text manipulation formulas to dynamically update prefixes while retaining the unique cell data.

Since SharePoint's built-in bulk editing functionality overwrites the entire selected value rather than modifying specific parts, exporting the list to a spreadsheet application allows you to use functions like IF, LEFT, FIND, and MID to conditionally build the correct strings.

Export the List

Navigate to your SharePoint list, click on 'Export' in the command bar, and select 'Export to Excel' or 'Export to CSV'.

Set up a Helper Column

Open the downloaded file in your spreadsheet application. Insert a new column next to the target data column (e.g., Column B) to act as a helper.

Apply the Formula

In the first data row of the helper column, enter your conditional formula. For example: =IF(OR(LEFT(B2,2)="SL",LEFT(B2,4)="SL21"),B2,IF(ISNUMBER(FIND("-",B2)),"SL21-"&MID(B2,FIND("-",B2)+1,LEN(B2)),"SL21-"&B2)). Adjust the cell reference (B2) according to your layout.

Review and Copy

Drag the fill handle down to apply the formula to the remaining rows. Review the generated text strings to ensure accuracy, then copy the calculated values.

Paste into SharePoint

Return to your SharePoint list and click 'Edit in grid view'. Select the top cell of the target column and paste the copied values. Verify the data before exiting grid view to save changes.

Pro Tip: Always make sure the number of rows you are copying from your spreadsheet exactly matches the number of rows visible in your current SharePoint grid view to prevent data misalignment.

Use WPS Spreadsheet for Advanced List Data Manipulation

While SharePoint limits partial bulk edits natively, exporting your list to a spreadsheet allows you to handle complex formula updates easily. WPS Spreadsheet provides a highly compatible, fast, and free alternative to Microsoft Excel for editing your exported SharePoint lists.

1. Open Exported Data: Launch WPS Spreadsheet and easily open the .iqy, .csv, or .xlsx file exported from SharePoint.
2. Process the Data: Utilize WPS Spreadsheet's advanced formula capabilities to set up your helper columns and manipulate text strings.
3. Seamlessly Copy Back: Copy the formatted data from WPS Spreadsheet and directly paste it into the SharePoint grid view without formatting conflicts.

Frequently Asked Questions

Can I bulk edit part of a text string directly inside SharePoint?

No, SharePoint's native bulk editing tool overwrites the entire value of the selected cells. To modify only a portion of a string or append prefixes while keeping unique data, you must export the list to a spreadsheet tool, calculate the new values, and paste them back.

Why am I getting an error when pasting data back into SharePoint's grid view?

Pasting errors in grid view usually occur if the target column is read-only, if there are data validation restrictions, or if the number of rows copied from your spreadsheet does not perfectly match the visible rows in SharePoint. Ensure your list view is not grouped or filtered out of order.

How does the formula prevent the loss of unique data?

Formulas like MID and FIND isolate the unique identifier within the cell (e.g., extracting everything after a hyphen) and then concatenate (using the & symbol) that unique portion with the desired standardized prefix, ensuring no original data is erased.
