What is bulk upload?
Bulk upload is the process of importing large volumes of data at once, typically from spreadsheet files (CSV, Excel), rather than entering records one at a time.
Understanding bulk upload
Bulk upload allows users to import hundreds or thousands of records in a single operation. Instead of manually entering data row by row, users prepare their data in a spreadsheet and upload the entire file.
Common bulk upload scenarios: - Customer imports: Uploading a list of customers from a CRM export - Product catalogs: Importing thousands of products with prices and descriptions - Transaction history: Loading historical data for reporting - User provisioning: Creating multiple user accounts at once
The challenge with bulk upload is handling the variety of real-world data: inconsistent formats, missing fields, typos, and edge cases. A good bulk upload solution validates data, highlights errors, and helps users fix issues before the data enters your system.

Frequently asked questions
How many rows can bulk upload handle?
It depends on the solution. Browser-based tools typically handle 10,000-100,000 rows. Ivandt uses web workers to process 500,000+ rows in the browser without freezing the UI.
What file formats should bulk upload support?
At minimum: CSV and Excel (.xlsx). CSV is universal but loses formatting. Excel preserves data types better. Some solutions also support JSON, XML, and Google Sheets.
How do I provide a good bulk upload UX?
Key elements: clear templates, drag-and-drop upload, progress indicators for large files, inline error display, ability to fix errors without re-uploading, and clear success/failure feedback.
