Fill the empty columns in the accounts sheet, site by site
An accounts sheet with empty columns is a to-do list nobody was assigned. Agent FM takes the assignment: for each row with gaps it visits the company's website and LinkedIn page and fills in industry, headcount range, city, and the one-line description. Where sources disagree it prefers the company's own site and notes the conflict; where it can't verify, the cell stays blank, because a blank is more honest than a guess. You get the count of rows completed and the companies that wouldn't confirm. The sheet becomes usable for the campaign it was built for, without anyone doing a day of archaeology one tab at a time.
Enrich [sheet, e.g. the Accounts tab of the CRM cleanup sheet]. For each row with gaps, visit the company website and LinkedIn page and fill in industry, headcount range, city, and the one-line description column.
Where sources disagree, prefer the company's own site and note the conflict in the notes column. Don't guess, leave a cell blank over inventing a value.
Tell me how many rows you completed and list the companies you couldn't verify.
