Tableau Integration in London
Connecting systems to Tableau for London organisations, where writing extracts programmatically changes what the platform can report on. Data that has no live connector — an internal API, a partner feed, a calculated result — can be published as an extract on a schedule, which brings it into the same environment as everything else.
Why this comes up
The problem
Data from an internal system is exported to a spreadsheet each week and refreshed into Tableau by hand.
What you get
What we deliver
- Extracts generated and published programmatically rather than uploaded manually
- Refresh scheduled against how often the source data genuinely changes
- Incremental refresh used where full rebuilds have become slow
- Published data sources used so workbooks share one definition
- Automation authenticated with a dedicated account rather than a person's login
- Failures alerted, since a stalled refresh serves stale data without complaint

Working in London
London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates.

Tableau Integration in London — common questions
- Why generate extracts programmatically?
- Because it removes the manual step and the person who performs it. Data without a native connector otherwise arrives through somebody exporting and uploading weekly, which delays it, introduces mistakes and stops entirely when that person is away.
- When is incremental refresh worth it?
- Once full rebuilds take long enough to constrain the schedule. Appending new rows rather than reconstructing the whole extract keeps refreshes short as data accumulates — with a periodic full rebuild to correct any drift from changes to historic rows.
- Should automation use a personal account?
- No. Automation authenticated as an individual breaks when they leave, change password or have their permissions altered, and it makes the audit trail misleading — a dedicated account with the necessary access is both more robust and clearer.
- How do we know a refresh failed?
- Only by monitoring it. A failed refresh leaves the previous extract in place, so dashboards continue to display data that looks current and is not — which is discovered when somebody notices a figure has not moved for a fortnight.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
