Overview
If multiple imports are uploaded using the same import name, the platform treats subsequent uploads as updates to the original import rather than creating a new, separate import. This behavior can cause records from multiple files to be combined into a single import.
Symptoms
You may notice one or more of the following:
Records from different CSV files appear in the same import.
Import totals are higher than expected.
An import contains data that was not included in the most recent file.
Multiple imports with the same name do not appear as separate imports.
Root Cause
The import process supports updating an existing import by uploading another file with the same import name.
When this occurs, the system assumes the new file is intended to modify or add to the existing import and combines the records on the back end instead of creating a new import.
Example:
The following files were imported using the same import name:
Because both uploads shared the same import name, the system treated them as a single import and merged the records.
Best Practices
To prevent imports from being combined unintentionally:
Assign a unique name to every import.
Include identifiers such as the date, version, or purpose in the import name.
Examples of good import names:
Premium Deposit - 2026-07-06Emails Only - V2Premium Deposit - July 2026Membership Import - Batch 01
Key Takeaway
Using the same import name signals the system that you are updating an existing import. To ensure each upload remains independent, always use a unique name for every import.
