Excel, CSV & Data Automation for Business Operations

About me
I take on defined operational problems: a spreadsheet that needs cleaning before import, a recurring task that should be automated, or a CRM process without clear ownership. Deliverables are agreed in advance and can include validated files, exceptions, instructions and a manual fallback.

I work on Excel/CSV data rescue, workflow automation and CRM operations.
For data work, I preserve the source, clean and validate the agreed fields, separate exceptions and provide a change log.
For automation, I map the current task, implement the agreed workflow, test it and document the manual fallback. CRM work covers stages, owners, next actions and reporting.
I also prepare validated data for ERP, CRM or e-commerce import to a supplied specification, without claiming vendor certification. Before work starts, we agree the inputs, scope, timeline, total price and acceptance check.
