Repeatable cleaning pipelines
Power Query or Python transformations you can rerun, not a one-time manual cleanup.

Hire an Excel data analyst in New York City.
The recurring New York data problem is entity matching: the same portfolio company, counterparty or property appearing under four spellings across a custodian file, an admin statement and an internal tracker. Totals agree, detail does not, and the difference only shows up in a drill-down.

Why New York City specifically
Where this work comes from.
Clients for this are typically in Midtown, the Financial District, Long Island City and Downtown Brooklyn, across investment and asset management, commercial real estate, media, and professional services firms billing by the hour. Deal models, portfolio packs and month-end consolidations that have to survive review.
For the wider picture of what we see in this market — the recurring problems, the source systems, how the time difference plays out — the New York City guide covers it properly rather than repeating it on every service page.

Questions
Excel data analyst in New York City — questions.
Answers for this service in this market, including the ones that might cost us the job.
Ask us something elseTwo systems disagree by a small amount every month. Is that worth fixing?
Usually yes, because a small recurring difference is rarely random — it is a rule difference that will eventually produce a large one. The useful deliverable is the explanation of why they differ, not a merged file that hides it.
Will I be able to run it again myself?
That is the point. Power Query steps are visible and rerunnable, and we document the process. If you would rather we run it each cycle we can, but you should not need us to.
How do you handle a model that has to be audit-ready?
We keep assumptions in one place, avoid hard-coded numbers inside formulas, add reconciliation checks that fail loudly, and write a short update procedure that lives in the file. None of that is exotic — it is just discipline that gets skipped when a model grows under deadline pressure.
