About this Gig
Tired of copy-pasting between spreadsheets? Send me your Excel or CSV files and get back one clean master file you can use right away.
What you get:
All your files and sheets merged into one workbook
Columns lined up, even when files use different headers
Exact duplicates removed, blank rows and extra spaces cleaned
Dates, numbers and text in one consistent format
A change summary of what was merged and removed (Standard and Premium)
How it works:
Step 1: Send your files (or a sample) and tell me what the final file should look like.
Step 2: I merge and clean them with tested scripts, not manual copy-paste.
Step 3: You receive the master file, ready to filter, pivot or share.
Why me:
Your original files are never changed - you get a separate, clean copy.
Every row is accounted for: the change summary lists what was merged, fixed and removed.
Same result every time, because the work is done by tested code.
Message me with a sample file and I will reply with a fixed price and delivery date.

FAQ
What files can you merge?
I can merge Excel and CSV files, including multiple worksheets and files with similar or slightly different column structures.
Can you remove duplicates and clean inconsistent formatting?
Yes. I can remove exact duplicates, clean blank rows and spaces, standardize headers, and normalize dates, numbers, and text where it is safe to do so.
Will my original files be changed?
No. I keep your original files unchanged and deliver a separate clean master file and, when included, a change summary.
Can you handle large files?
Yes. Files with tens of thousands of rows are fine. For very large data or many files, message me first so I can confirm price and timing.
Do you work with Google Sheets?
Yes. Download each sheet as .xlsx or .csv (File > Download) and send it. I deliver an .xlsx file you can upload straight back to Google Sheets.
Is my data kept private?
Yes. Your files are used only for your order, never shared, and deleted from my computer 7 days after delivery.
Can I get the script to repeat the merge myself?
Yes. If you merge the same kind of files every week or month, message me and I will quote a small reusable tool.
