What is FedEx Ship Manager's CSV import row limit?

FedEx Ship Manager supports up to 999 shipments per CSV import file. Order exports with more than 999 rows must be split before upload to avoid import errors.

Will recipient address and service level data be preserved exactly?

Yes. The tool performs only structural splitting — no address fields, service codes, weights, or any other cell values are modified.

Can I use this for 3PL inbound receiving or ASN files?

Yes. Any logistics CSV — outbound shipments, inbound ASNs, inventory transfers, or freight manifests — can be split by row count using this tool.

Does the tool work with CSVs exported from ShipStation, ShipBob, or similar platforms?

Yes. CSVs exported from any shipping or fulfillment platform are standard CSV files and fully compatible. The tool does not require any platform-specific formatting.

What happens if a split file is missing the header row when uploaded to a carrier portal?

The carrier portal will fail to map columns and either reject the file or create malformed shipments. Deliteful includes the header row in every output chunk automatically to prevent this.

Split Shipment and Order CSVs Into Carrier Portal–Ready Batch Files

Logistics coordinators uploading bulk shipment orders to carrier portals — FedEx Ship Manager, UPS WorldShip, DHL's bulk upload tool — hit file size and row count limits constantly. FedEx Ship Manager's CSV import caps at 999 shipments per file. When your daily order export from the WMS runs to 5,000 lines, you cannot process it in one pass.

High-volume shipping operations — third-party logistics providers, fulfillment centers, wholesale distributors — generate order exports that routinely exceed carrier portal limits. The standard workaround is to filter and export in batches from the WMS or OMS, but that requires database access or system configuration changes. Splitting a flat export after the fact is faster and requires no backend access.

Deliteful splits your shipment or order CSV into fixed-row chunks with the header row preserved in every output file. Carrier portal importers use the header row to map tracking number, recipient address, weight, and service level columns — a missing header means a failed batch and delayed label generation. Set your limit to 999 for FedEx, 1,000 for UPS, or your 3PL's documented cap, and download numbered output files ready for sequential upload.

How it works

1
Export the order or shipment CSV from your WMS or OMS
Pull the full shipment batch export — order numbers, recipient addresses, weights, and service levels — from your warehouse or order management system.
2
Set the row limit for your carrier portal
Use 999 for FedEx Ship Manager, 1,000 for UPS WorldShip, or check your 3PL's bulk upload documentation for its specific file limit.
3
Upload each numbered chunk to the carrier portal
Each output file includes the required header row — upload sequentially and generate labels for each batch before moving to the next.
