Does Deliteful preserve the folder structure inside ZIP archives?

Yes. The original internal directory hierarchy is preserved exactly on extraction. If vendor files are organized into subdirectories inside the ZIP, that structure is maintained in the extracted output.

What happens when one archive in a batch is corrupted?

Corrupted archives are detected during pre-extraction verification and skipped. The remaining archives in the batch continue to process normally, so a single bad file does not block the entire delivery.

Can I process multiple vendor ZIPs in one batch?

Yes. Batches support up to 50 files or 2 GB total, whichever is reached first. Each ZIP is extracted into its own isolated directory to prevent filename collisions across deliveries.

Is there a limit on how large the extracted content can be?

Yes. Total extracted output is capped at 5 GB per task. Archives that would exceed this limit are skipped rather than partially extracted, protecting against zip bomb-style oversized deliveries.

Extract Vendor ZIP Deliveries for Data Pipeline Ingestion

Data engineers frequently receive ZIP-packaged data deliveries from vendors, partners, or legacy export systems — often on irregular schedules and without reliable quality guarantees. Deliteful extracts these archives server-side, preserves the internal folder structure, and skips corrupted files automatically, so ingestion pipelines receive clean, organized output without manual intervention.

Vendor data deliveries packed as ZIPs present two recurring problems: inconsistent internal structure that breaks downstream path assumptions, and occasional corruption that causes local unzip commands to fail mid-batch. When a nightly ETL job depends on a successfully extracted file set, a single bad archive stalling the whole process is a real operational cost. Deliteful skips corrupted archives and continues processing the rest, returning a clean output set.

The original folder hierarchy inside each ZIP is preserved on extraction — critical when downstream ingestion scripts reference relative paths like 'data/2024/Q1/transactions.csv'. Extracted output is returned as a downloadable bundle. The 5 GB extraction cap per task accommodates most vendor delivery sizes while preventing runaway decompression from oversized archives.

How it works

1
Upload vendor ZIP deliveries
Upload up to 50 ZIP files or 2 GB per batch for bulk extraction.
2
Structure and integrity validation
Deliteful verifies each archive and flags corrupted files without stopping the batch.
3
Download extracted, structured output
Receive files in their original folder hierarchy, ready for pipeline ingestion.
