Pasting dates from Excel or Google Sheets does not work in date cells #541
Description
When pasting dates from Excel, SharePoint Excel, or Google Sheets into a ReactGrid date column, none of the dates are recognized. The pasted cells show blank or Invalid Date.
This occurs regardless of whether the day is single-digit or double-digit.
To Reproduce
Steps to reproduce the behavior:
- Copy a column of dates from Excel, SharePoint Excel, or Google Sheets (example below).
11/6/2025
11/10/2025
-
Paste them into a ReactGrid date column.
-
Observe that the cells remain blank or contain Invalid Date.
Environment:
ReactGrid version: 4.1.17
Browser: Chrome
OS: macOS
Additional context / Notes
The root cause seems to be how handlePaste parses clipboard data:
