How do I merge Excel files?
Sometimes you need to consolidate multiple data downloads (e.g. from Tally, Zoho, or GST Portal) into one unified file for tallying or offline preparation. Our free merge tool combines all the sheets from each selected file into one large workbook. If you upload 3 files with 2 sheets each, you will download 1 file with 6 sheets.
Frequently Asked Questions
How do I merge multiple Excel files online safely?
You can drag and drop multiple Excel files into our tool. It merges them into a single workbook offline in your browser, guaranteeing your data privacy.
Why merge Excel files for GST filing?
Businesses often download multiple GSTR-2B, error reports, or branch-wise sales data. Merging them into one master Excel file makes reconciliation and filtering much easier.
Does the tool preserve Excel sheets during merging?
Yes. Our tool can either append data from identically named sheets together or combine different files into separate sheets within the master workbook.
Is there a limit to how many files I can merge?
There is no hard limit on the number of files, but merging dozens of massive files may consume significant browser memory.
Do I need to install any software to merge files?
No installation is required. The merging process uses WebAssembly and JavaScript directly in your web browser.
Does it support .csv and .xlsx formats?
Yes, our tool supports both modern .xlsx files and standard .csv files, converting them seamlessly into one output format.
Will the formatting of my Excel files be lost?
Basic data and structure are perfectly preserved. However, complex macros, charts, or advanced conditional formatting may not carry over during the merge.
Are my merged files stored on your servers?
Absolutely not. The entire file reading, merging, and downloading process happens on your local device.
Is the Excel merge process secure?
Yes, the merge process is 100% secure. Everything happens locally within your web browser. Your confidential data is never uploaded to our servers.
Is there a limit on how many Excel files I can merge?
Since processing is done by your browser, it largely depends on your system memory. Typically, merging up to 50-100 files of moderate size works seamlessly.
