Support data collection and reporting

I need a single workbook that my team can use to collect weekly lab measurements from five field sites and produce one clean report for Monday morning. Combine the raw sheets I get from Anna, Jamal, Priya, Marco and Li into a reporting tab that shows each site’s last seven days, flags missing readings, and calculates the site average and standard deviation. Send it to me for a quick completeness check before I export the PDF for management on Monday.

Before I hand this to the monitoring team, make the week’s trends obvious and reduce entry errors. Put the site average and a red missing-data badge in the top-left of the report, show a sparkline for each site’s seven-day trend next to its name, lock the cells I don’t want changed, and add a simple validation rule for the measurement column that rejects values outside historical limits.

I just merged Anna, Jamal, Priya, Marco and Li’s CSV exports for the week and Site D’s standard deviation is three times normal. I don’t know if that is a true spike, a unit conversion error from Marco, or duplicate timestamps from Jamal. I’m worried management will panic if I hand this up. What’s the fastest sequence of checks I should run to diagnose the cause and what’s the best way to present my provisional finding to the lab manager so we don’t overreact?

Every Monday we lose three hours reconciling different CSV formats, time zones and column names from the five sites. It eats our day and invites mistakes. Tell me one habit to stop and one repeatable file-check I should impose on the senders so we can cut that time in half and avoid last-minute fire drills.
