What usually breaks your CSV import: formatting or duplicates?

CSV cleanup problems tend to fall into two buckets:

1. File-format issues — wrong delimiter, legacy encoding, quoted multiline cells, or uneven rows.

2. Data-quality issues — exact duplicates and near-duplicates such as nickname or spelling variants.

I built CSV Repair & Deduper because both often need attention before a CRM, storefront, or mailing-list import. It runs locally in your browser and lets you review suggested duplicate removals before changing anything.

Which problem costs you the most time?

- The destination app rejects the file

- The import succeeds but creates duplicate records

- Characters or columns are corrupted

- Something else

If you share the destination app and error type (please do not share private data or files), I’ll use the responses to prioritize support notes and fixes. The product launches later today at $19 once, with no subscription.
