I keep one master report in Excel and every week I receive three supporting reports, also in Excel. I need a reusable template or automated routine that will: • Pull the latest data from those three supporting workbooks. • Append any new entries and update any existing rows in the master (no need to handle deletions). • Standardise every date field to one consistent format. Beyond that logic, there are a few simple addition/subtraction calculations inside the sheet that must continue to work once the data refreshes. I am happy for you to tackle this with Power Query, VBA, formulas, or whichever Excel-native method you feel delivers a one-click refresh. When you are done, I will need: 1. The completed template/master file wired to accept the three source files splitted into two reports maintained based on site code column 2. Clear, concise instructions (written or short screen-share recording) so I can run the weekly update myself without tweaking code. Accuracy in the merge rules for new and updated records and spotless date formatting are the key acceptance criteria.

Hello, I can set this up so your weekly update becomes a simple one-click refresh instead of a manual merge. I’d likely use Power Query because it’s reliable for pulling from the three Excel reports, matching existing records, appending new ones, and keeping dates consistent without unnecessary VBA. I’ll also split/maintain the two required reports based on the Site Code column and make sure your existing addition/subtraction calculations continue working after every refresh. Before delivery, I’ll test the process with multiple updates and provide simple instructions so you can run it yourself each week. Please share the master and three sample reports. I’ll first identify the safest unique key for matching records. Best regards, Ayaz Akhtar

Hi from South Africa! I read your project description with great interest, and wondered if you would consider having this work done in Microsoft Access, which would be a great application for managing your data. I am an experienced Access developer and specialize in creating custom apps for small to medium sized businesses, from entire production systems, to smaller apps to assist with tasks as per your project description. Access typicall offers user-friendly input forms, but under the hood has great functionality for doing the importing, appending, and reporting that you require. If you are interested, I could build a quick demo using sample data to show you how Access would process your information, but also protect formulas and data from being accidentally changed. Please get in touch if you have questions for me, or would like me to work with you on your project. Kind regards - Carolina

Hi, I can build a clean Excel-native refresh workflow for your weekly reports so the master file updates reliably with one click. I’ll structure the workbook so it can pull from the three supporting Excel files, append new rows, update existing records, and keep all date fields standardized. I’ll also preserve your existing in-sheet calculations so they continue working after each refresh. If needed, I can use Power Query, VBA, or a formula-driven approach, whichever gives you the most stable result for your process. I’ve worked on Data Analysis and Data Processing workflows in Excel, and I pay close attention to merge logic, repeatable automation, and clear handoff instructions. I’ll make sure the final template is easy to run each week with minimal effort. Would you like the refresh to match records by a unique ID only, or by site code plus another key? I can deliver the completed master/template file plus concise instructions or a short walkthrough so you can run it confidently. Best, Miguel

Hi, This is a clean Power Query job — the right tool for a repeatable merge with one-click refresh and zero code maintenance on your side. What I will build into your master file: 1. Three-Source Ingestion: queries pointing at the three supporting workbooks (fixed paths or a drop-in folder — your choice), pulling the latest data on every refresh. 2. Merge Logic: new entries appended, existing rows updated by their key — no deletions handled — with the split-by-site-code routing included so each report lands in the right section of the two outputs. 3. Date Standardisation & Safe Calculations: every date field normalised to one consistent format at load time, and your existing addition/subtraction formulas re-anchored so they keep working after each refresh. You will receive the wired master template plus a one-page instruction sheet (optional short recording) so your weekly update is a single Refresh All click. I am available right here in chat to confirm the row-key column and your preferred refresh method.

Hi, I can build a reliable, reusable Excel solution that turns your weekly three-workbook update into a simple one-click refresh. I understand the key requirement is to accurately merge the latest supporting data into the master—adding new records and updating existing ones, while leaving deletions out of scope. I’ll also ensure all date fields are standardized consistently and that the existing addition/subtraction calculations continue working correctly after every refresh. I can implement this using Power Query, VBA, or a combination of Excel-native tools, depending on which approach best fits your current workbook structure. The solution will also handle splitting the resulting reports into the two required reports based on the Site Code column. My approach will include: -Connecting the master to the three supporting workbooks. -Building reliable matching logic for new versus existing records. -Updating existing records without creating duplicates. -Standardizing date fields throughout the imported data. -Preserving and validating the existing calculations. -Configuring the workflow so the weekly process requires minimal manual intervention. -Testing the merge logic with new and updated records to ensure accuracy. The priority will be accuracy, repeatability, and making the weekly update as straightforward as possible. Best regards,

A reusable one-click Excel routine that pulls three supporting reports, updates/merges the master by site code, formats every date consistently and keeps your calculations working is exactly the kind of automation I build weekly. Power Query or VBA — I'll pick whichever gives you a true one-click refresh. Three things before I quote: 1. Do the three source files keep the same structure every week, or do columns shift? 2. What's 'updated' for an existing row — by site code alone, or by a row key combination? 3. Where do the files land (folder path), and should new entries preserve any manually-added columns you maintain? Scope: build the refresh routine -> wire to the three source files -> standardized dates -> preserve your formulas -> clear written + short screen-share instructions so you run it weekly alone. 4.9/5 from 153 reviews — automations I hand over come with instructions you can follow. Reply with the 3 answers and I'll confirm the method and timeline.

Managing three weekly source files with manual merges is exactly where formulas break and dates end up in mixed formats sounds like Power Query is the right call here since it handles refresh-and-append natively without any VBA maintenance headache. My approach: build a Power Query pipeline that pulls all three workbooks, applies consistent date parsing (M/D/YYYY or your preference), matches on a unique key to append new rows and update existing ones without touching deletions, then splits output into two reports by site code. Your addition/subtraction formulas stay untouched since they'll reference the refreshed table, not static ranges. One-click "Refresh All" when done. I'll also record a short screen-share so you're not stuck maintaining code. What's the unique identifier across your three source sheets invoice number, ID column, or something else?

THIS IS A GREAT MATCH. I have just developed an Excel automation template that consolidates multiple data sources seamlessly. The goal is to ensure your master report updates effortlessly with new entries and maintains accurate calculations. Using Power Query would streamline the data pulling, while clear date formatting is a common pitfall that I will ensure is flawlessly handled. The process will be straightforward and user-friendly, making your weekly updates a breeze. MESSAGE ME, I WILL KEEP THIS SIMPLE. Regards, Stefan.

Hi, Your weekly Excel process needs a reliable one-click refresh that pulls three source workbooks into a master, updates existing rows, adds new ones, and keeps dates consistent without breaking calculations. I can set this up in Excel using Power Query or a lightweight VBA routine, depending on which gives the cleanest refresh for your files. I’ve built similar Excel workflows where source data changes weekly and the master must stay stable, including merge logic, date standardisation, and preserving formulas after refresh. My focus would be accuracy in the row matching, predictable refresh behavior, and a simple handoff you can run yourself. I’d structure the template so the three inputs are easy to swap, the site code split is handled cleanly, and the formulas continue working after each update. If helpful, I can build this into a clear template and provide short instructions for your weekly run. Best regards, Gabriel
