I’m pulling together a clean master file of information that currently lives inside several online databases. The work is pure text data transfer—no numbers to crunch—so what I need is a careful set of eyes to copy each required field exactly as it appears and paste it into the template I’ll share (Google Sheet or Excel, your choice). You’ll receive a list of database URLs plus the login credentials where needed. For every record, simply: • Open the link, locate the text fields I flag (titles, descriptions, notes, etc.). • Copy them without altering spelling, spacing, or punctuation. • Paste each field into the matching column in the sheet and mark the row complete. I’ll spot-check accuracy daily, so a meticulous approach is ...
