About this Gig

I turn a repetitive CSV reporting task into a reusable local tool. It reads one agreed CSV template, applies your specified rule, and produces an output file plus a list of rows that need attention.


Basic package includes:

One CSV input template and one processing rule

Output CSV and exception list, for up to 1,000 rows

Source code and a short guide to run and check the result

One revision within the agreed scope


Before ordering, please message me with an anonymized sample, your rules, and an example of the expected output. I will confirm that the Basic package fits your task. My gallery uses synthetic data and shows a portfolio demo, not a paid client project.


This package covers CSV files only. XLSX workbook editing, website login, API connections, cloud deployment, scheduled operation, new rules, and extra templates need a separate custom offer. Please remove personal and confidential information from samples.
