Dear Customers,
We would like to inform you of an important upcoming change to our SpreadJS npm packages.
Starting with SpreadJS v19, the legacy npm package @grapecity/spread-sheets will no longer be published or maintained. All new versions of SpreadJS will be released under the new scope @mescius/spread-sheets.
Existing versions of @grapecity/spread-sheets will remain available on npm, but they will not receive further updates, bug fixes, or technical support. To continue receiving the latest features, security updates, and support, we strongly recommend migrating to @mescius/spread-sheets.
Be sure to install @mescius/spread-sheets to take advantage of the latest and greatest features from SpreadJS!
For step-by-step migration details, please refer to our NPM Package Migration Guide: https://developer.mescius.com/spreadjs/docs/getstarted/npm-package-migration-guide
If you have any questions or need assistance with the transition, please don’t hesitate to contact our support team here: https://developer.mescius.com/support/contact
All the Best,
SpreadJS Product Team
