Hi, I can prepare and transform your mixed structured and unstructured dataset, handling cleaning, normalization, missing values, inconsistencies, and analysis-ready modeling in Power BI. I’ll build clear visuals including spotlight/doughnut charts and decomposition trees, then use bookmarks to surface meaningful comparisons and insights. The final report will include concise dataset context, validated findings, and an organized visual narrative. A few questions: What formats are included in the unstructured data? Are the required Power BI visuals already specified? Should the report include a specific number of bookmarks? Best regards, Muhammad Usman

Good day! Turning a mixed dataset into a reliable Power BI report requires more than cleaning columns—it’s about transforming inconsistent structured and unstructured data into a model that produces meaningful insights. I can handle the preparation, cleaning, transformation, and reporting workflow from start to finish. With 9 years of experience in data analysis and reporting, I can use Power Query and Power BI to structure the dataset, resolve inconsistencies, handle missing or duplicate data, and build clear visualisations including doughnut/spotlight charts, decomposition trees, and other relevant visuals. I’ll also analyse the bookmark-driven views and turn the resulting insights into useful report content. The final report will be organised, visually clear, and supported by concise introductory content explaining the dataset and key findings. I can take ownership of the complete data-to-dashboard workflow and turn the raw dataset into a polished, insight-focused Power BI report.

@Aaleen110

The mixed dataset, structured and unstructured, means the initial data loading and cleaning needs careful handling, so I'd use Python with Pandas for that part, getting it all into a consistent state before Power BI. Then I'll build the Power BI model, focusing on those decomposition trees and also the spotlight/doughnut charts you mentioned, making sure the bookmark inferences are set up to respond correctly to user interaction. I would build the data cleaning and transformation steps first, using Python libraries, so that the Power BI model is built on clean, reliable data from the start. What is the expected final format for the report and visualizations? PDF, a live Power BI service link, or something else? I am a Preferred Freelancer on Freelancer with a 5.0 rating, 100% on time and 100% on budget. I need the dataset files to start.

@ImranAli01

Hi There, I got that you need a mixed structured and unstructured dataset cleaned, transformed, analyzed, and presented in Power BI with clear visuals, including spotlight/doughnut charts, decomposition trees, and bookmark-based insights. This is what I can help you with, let's chat. My approach is to use Power Query in Power BI to profile, clean, standardize, and transform the datasets before building the analytical model. I’ll then create interactive visuals and use bookmarks to present different analytical views and highlight meaningful inferences. The result will be a clean, reliable report where users can explore the data easily and understand the key findings without unnecessary complexity. As final deliverables you will receive the prepared and transformed dataset, Power BI report with the requested visuals, bookmark-driven insights, and a concise introductory section describing the dataset and analysis. I’ll also ensure the report is clearly structured, visually consistent, and easy to navigate. One thing I'd like to confirm before we start: will you provide the structured and unstructured datasets together with any required report format? Cheers, Imran

Jumping straight into it — mixed datasets usually get messy fast, but I’m used to cleaning structured tables and extracting usable fields from unstructured text before shaping everything for Power BI. I’ve built reports with spotlight visuals, doughnut charts, decomposition trees and bookmark‑based insights that read clearly in a final report. I’d start by profiling the raw data, creating a clean model, then building the visuals and narrative intro you need. Quick checks: which unstructured formats are included? do you already have a data dictionary? should bookmarks highlight trends or specific KPIs? Juan Pablo

@carlosd178

Hello, As a result of reviewing your project requirements carefully, I understand you need end-to-end data preparation for a mixed structured and unstructured dataset, followed by a clear Power BI report with meaningful visual analysis and documented insights. I have experience with data cleaning, transformation, statistical analysis, Power Query, data modeling, DAX, and Power BI dashboard development. My approach would first profile and standardize the dataset, handle missing values, duplicates, inconsistent formats, and unstructured fields, then build a clean data model ready for analysis. For the report, I can create doughnut/spotlight-style visuals, decomposition trees, interactive filters, drill-throughs, bookmarks, and concise written inferences explaining what each key view reveals rather than only presenting charts. I have a couple of quick questions. • What format is the source dataset currently in? • Do you already have specific KPIs or business questions the report should answer? I’m available to start immediately and can deliver both the cleaned dataset and a polished, easy-to-navigate Power BI report. Best regards, Carlos
