I have several digital files—specifically Excel sheets—containing pure text data that must be transferred into a consolidated workbook. The job is simple in concept yet detail-heavy in practice: every cell needs to match the source exactly, with spelling, spacing, and capitalization preserved. You will receive the Excel files, along with a template of the final master sheet. Your task is to copy or re-type the text into the corresponding columns, check for duplicates, and keep the overall structure intact. A quick turnaround is appreciated, but accuracy is non-negotiable; one misplaced character skews our internal searches and reports. Once finished, send back the updated master workbook and a brief note confirming the total number of rows you entered so I can cross-check...

Any approach that yields a correct result is acceptable to me. Deliverables: • The active phone number associated with the supplied username • A concise explanation of the steps, toolset or workflow you used, so I can replicate the process later if necessary Please let me know your estimated turnaround time and any information you require to get started.

I regularly receive a single-page payment advice in PDF format showing only the UTR code. I need a lightweight tool that can take that PDF, pull out the UTR, query the SWIFT network, and return the full trail of the funds—every intermediary bank involved, time stamps, references, and the final credit to our account. Complete transaction history is essential; basic origin/destination details are not enough. A simple command-line script, small desktop utility, or slim web interface is fine as long as it: • ingests the PDF directly (or manual re-typing) • resolves the UTR through SWIFT and maps each hop in the chain • outputs a clear, human-readable report

I need our Shopify store feeding cleaner, more complete data back to Meta by moving the key pixel events—Purchases, Leads and Add to Cart—into the Conversions API and making sure they deduplicate properly against the browser pixel.

I have a series of Customer-Experience (CX) reports that were built by someone else and I’m running into two persistent headaches: the layouts never look quite right and the whole thing slows to a crawl whenever I refresh or filter the data. I’d like you to dive into the existing codebase—whatever language or mix of SQL, Python, R, or something else it was written in—and clean it up so the reports render cleanly, run quickly, and draw from a richer, better-structured data set. Here’s what I need from you: • Audit the current report logic and pinpoint the root causes of the formatting problems and performance issues. • Refactor or rewrite the underlying scripts/queries so visuals line up perfectly and refreshes complete in a reasonable time. &b...

I need my existing Google Sheet to double as a live barcode scanner that talks directly to our Flipkart VMS. When a package’s barcode is scanned—either with a phone camera or a handheld scanner—the sheet should instantly fetch and record the correct Product ID from Flipkart so I can track every item the moment it hits the packing table. The flow I’m picturing is simple: 1. Cursor lands in the “Scan” cell. 2. Barcode is read. 3. Apps Script (or an add-on you build) calls Flipkart VMS, grabs the matching Product ID, and drops it in the designated column—no extra clicks. All logic, API calls, and error handling have to sit neatly inside the sheet so the packing crew keeps working in one tab. I also need a short set-up guide so I can duplicat...
I maintain several Excel workbooks that capture our customer information, yet the records are spread across multiple sheets and new entries arrive every day. I need a skilled hand to handle straightforward data entry—copy-pasting, validating, and aligning each field so every customer sits neatly in the right column of a single, master sheet. Here is what I expect once you’re done: all customer names, contacts, purchase notes, and any other existing columns correctly transferred, no duplicates, and one tidy table ready for filters, lookups, or future analysis. You are free to rely on formulas, Power Query, or basic VBA snippets if that speeds you up; accuracy and consistency, however, are non-negotiable. Please let me know how quickly you can turn the current batch around and ...
I want a specialist who can take from a blank slate to a production-ready CRM engine.

Once the data is streaming, you will design end-to-end lifecycle journeys that cover onboarding, retention and reactivation (happy to refine the exact stages together). With reliable data in place, I need dynamic audience segments that update automatically—behaviour-based, demographic or purchase-driven, whichever proves most actionable—so every message is context-aware. You will architect the visual workflows, define trigger logic, write the emails/push notifications, and set up A/B tests to keep iterating toward higher conversion. Co...
