A browser-based tool that turns 3 LinkedIn CSV exports into a professional Word report in 3 clicks. No server, no login, no install.
The AGC LinkedIn Reporting Tool is a browser-based application built for a French architecture firm. The user drops three LinkedIn CSV exports (posts, followers, engagement) into a single HTML page and receives a fully formatted Word report with branded headers, calculated metrics, and commentary-ready sections. No server, no login, no install. Works entirely offline in the browser.
AGC Architectes, a French architecture firm, ran a monthly LinkedIn reporting ritual for their leadership team. The marketing person exported three CSV files from LinkedIn Analytics (posts, followers, engagement), pasted them into an Excel template, calculated metrics by hand, formatted a Word document, and sent it out. It took between two and four hours per report. Every month.
The reports were important. Leadership used them to decide content direction and measure whether the LinkedIn investment was working. But the production was mind-numbing, error-prone, and the person doing it had no appetite for automation tools that required learning new software or uploading internal data to the cloud.
The constraint was strict: no cloud, no login, no installation, no server. The firm\'s IT policy did not allow any of it. The tool had to run on a laptop, offline, without leaving a trace.
The solution was a single HTML file that runs entirely in the browser. Open it, drag the three CSVs onto it, click "Generate Report", and a fully formatted Word document downloads to the laptop. No network calls, no cloud, no login. The file can live on a USB stick or a Desktop folder and it just works.
Under the hood it uses vanilla JavaScript for CSV parsing and metric calculation, plus a Word-compatible HTML renderer that outputs a .docx with the firm\'s branding baked in. No frameworks, no build step, no dependencies. A single .html file plus two image assets for the branded header.
The report structure was designed around the actual decisions the leadership team needed to make. Top-performing posts. Engagement trends. Follower growth. Hashtag performance. Competitor snapshots if a competitor CSV was also provided. Nothing extra.
The technical story here is small. One HTML file, one client, one workflow. But the principle is worth keeping: not every AI or automation problem needs a cloud platform. When the constraints are strict, the right answer is often the simplest one. The firm now runs the tool every month with zero ongoing cost, zero account management, and zero dependencies.
