Convert structured information from PDF documents into an accurate Excel workbook. The documents may include tables, invoices, or survey records. The freelancer must preserve the original meaning, identify unreadable fields, and perform a second accuracy check before submitting the completed file. The successful freelancer will be expected to work independently, share progress at agreed checkpoints, and raise questions early when a requirement needs clarification. All submitted work should be original, well organized, and ready for practical use after reasonable review.
