Google Sheet Data Entry Update

I need to bring an existing Google Sheet up to date by manually entering data that currently lives in several plain text (.txt) files. I will supply the text files and grant access to the spreadsheet; your job is to copy every record into the correct columns, preserve the sheet’s current structure, and double-check for typos or misplaced values. No new formulas, formatting tweaks, or design changes are required—this is strictly accurate data entry from digital text sources.

Accuracy is critical, so I will spot-check the finished sheet before approval. Once you review a sample file, let me know how quickly you can deliver; I’m aiming for a prompt turnaround within the next few days.

Deliverables
• Updated Google Sheet (or Excel, if you prefer) containing all information from the supplied text files, aligned with existing headers.
• Brief note flagging any lines that were unclear or unreadable in the source files.

Please share a sentence or two about similar work you have handled and your estimated completion time.
