Terms of Service

Last updated: November 13, 2026

The service

MergeExcel merges multiple spreadsheet files (.xlsx, .xls, .csv) into one workbook, on a subscription basis, and lets you download the merged workbook plus an audit report. Three merge modes are offered: Separate sheets (one sheet per file, kept as-is), Append rows (tables stacked by matching column headers, with optional deduplication), and Merge by ID (rows with the same ID are combined and every distinct value is kept). The merged workbook is a plain .xlsx file you can open in Excel, LibreOffice or Google Sheets. The exact result — row counts, duplicates removed, skipped rows — is always shown on the report page before you download.

Plans and limits

Each plan has a monthly allowance of merges, a per-merge file count and a per-file size limit, as shown on the pricing page. Usage is counted in merges: one successful merge costs one run. Allowances reset at the start of each calendar month and do not roll over. Failed runs never count. Merge by ID and downloading the audit report CSV are included in the Starter and Pro plans; the Free plan shows the audit summary on the result page. We enforce limits on the server; attempts to bypass them may lead to suspension.

Your files and responsibilities

• You must have the right to upload and process every file you submit.
• The merged workbook is generated from the files you upload. You are responsible for checking it and for keeping your own master copy of your originals.
• Do not upload malware, or files designed to exploit the service.
• Uploads and results are deleted 72 hours after processing; keep your own copies.
• Workbooks may contain other people's personal information. Only upload files you have the right to process.

Accuracy

Merging is automatic and follows the column headers in your files. Headers that differ in spelling are treated as different columns, and rows are matched by the ID column you name in Merge by ID mode — always check the merged workbook and the audit report before you rely on it, publish it, or send it. The service is provided "as is" without warranties of fitness for a particular purpose, and it is not legal, medical or accounting advice.

Payments and cancellation

Paid plans are billed monthly through Paddle, our merchant of record. You can cancel at any time; the plan stays active until the end of the paid period and then returns to the Free plan. Refunds follow our refund policy.

Liability

To the extent permitted by law, our liability for any claim arising from the service is limited to the amounts you paid us in the twelve months before the claim. Nothing in these terms limits liability that cannot be limited by law.

Changes

We may update these terms; material changes will be announced on this page with a new "last updated" date. Continued use after a change means you accept the updated terms.
