Data Analysis is a process of collecting and examining data in order to gain meaningful insights and inform data-driven decisions. Data Analysts utilize a range of techniques to discover useful patterns, trends, or relationships demonstrated by large amounts of data.

    I’m building a piece of software whose sole focus is signal processing and I need a developer who can take it from concept to a clean, working application. The core of the job is to create routines that can ingest raw signals, run frequency-domain analysis (FFT, filtering, spectral visualisation, etc.), and output both numeric data and easy-to-read plots in real time. I haven’t locked the project to a single operating system, so if you prefer to target Windows, macOS or Linux, let me know which toolchain and libraries you’d use and why.

    I’ve built a lightweight Chrome extension that adds Excel-style shortcuts and full-colour tabs to Google Sheets, and I’m ready for real-world feedback. (, ) If you spend a lot of your time inside Sheets running formulas and functions, you’re exactly the type of user who can push the add-on hard and tell me where it shines or falls short. (Bookkeepers, Accountants, Data Entry and Admin professionals I'm talking to you!) Here’s what I need you to do: 1. Install the extension from a private link I’ll provide. 2. Use it in your normal workflow for at least one live file (financial models, reconciliations, management reports—whatever you already do in Sheets). 3. Keep an eye on how the keyboard shortcuts, colour-coded tabs, and any performance...

    I have a set of figures that need to live in one clean, well-structured Excel workbook and then be transformed into a single, polished bar graph that compares six to ten categories. After you key the data into Excel, I’d like you to style the sheet for clarity—consistent number formatting, named ranges, and easy-to-read headings—so anyone opening the file can understand it at a glance. From there, please design a visually striking bar chart (the only chart type I need) that highlights category-to-category comparisons. Thoughtful colour choices, legible axis labels, and an unobtrusive legend are important; the goal is to make differences pop without overwhelming the viewer. Feel free to use Excel’s built-in chart tools or Power Query/PivotChart features if they spee...

    Scope is intentionally small; optimize for clarity and easy handoff in Python. Add lightweight error handling; fail with messages that help debug input paths and API responses. The Python work centers on: Google Sheets API sync. Confirm Python version (3.10+ is fine) before you start if anything is unclear. Tech stack: Python 3 only. Reference batch ID: QA-PY-0125.

    Deliver production-leaning Python: readable names, small functions, and a requirements file if needed. Keep dependencies minimal; pin major versions in when you add packages. The Python work centers on: barcode label printer script. Synthetic/sample inputs are enough for the demo run—no live production keys required. Tech stack: Python 3 only.

    The purchase history for my customers is still sitting in printed order forms and receipts, some of which include handwritten notes in the margins. I want every transaction re-keyed into a clean, well-structured spreadsheet (Excel or Google Sheets is fine) so I can finally run reports and analyse trends. Accuracy matters more than speed. You will be working from scans/PDFs of the originals; a handful of pages have handwriting that must be interpreted and entered exactly as written. If something is unclear, flag it rather than guessing—I will be available to clarify. Deliverables • One spreadsheet containing all purchase history, organised by the fields shown on each form • Consistent formatting for dates, currency and product names • A short log of any illegibl...

    I am looking to have a single Google Sheet that lets my company run day-to-day operations without jumping between multiple files. The sheet should give us dedicated areas for inventory tracking, employee scheduling, and sales / revenue reporting, then pull everything into a clean summary dashboard so we can spot issues or trends at a glance. Here is what I have in mind: • Separate, well-labeled tabs for Inventory, Scheduling, Sales, and an executive Dashboard. • Built-in formulas, data validation, dynamic charts, and pivot tables that update automatically as we add new rows. • Conditional formatting or simple Apps Script triggers (email or cell-colour alerts are fine) whenever stock dips below reorder levels, shifts overlap, or sales targets are missed. • Drop-do...
