The Scenario
The data cleanup wrapped up last week. A contractor spent three weeks working through 200 customer records — corrected emails in column C, updated phone numbers in column D, sevdesk contact IDs in column A. The spreadsheet is verified, signed off, and sitting in the office manager's Excel. The mandate: push every correction into sevdesk before the end of the week so the next invoice run uses the right contact information.
The bad version:
- Open sevdesk, navigate to Contacts, search for the contact by name (the sheet has IDs, not names, so you need a cross-reference), open the record, click Edit, update email, update phone, save.
- The cross-reference lookup adds 30 seconds per record. For 200 records, that's 100 minutes of lookup alone, before any editing.
- By record 80, you make a copy-paste error and put the phone number from row 81 into row 80's contact. You find this two weeks later when a client says they're receiving someone else's texts.
The corrections are done. They've been QA'd. The data is in the workbook. Getting it into sevdesk should be a one-step operation.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside Excel that reads your correction workbook and pushes updates to sevdesk contacts in one pass.
Read my Contact Corrections Excel sheet and update every sevdesk contact listed in column A with the new values in columns B through F
What You Get
- Each sevdesk contact updated with the corrected values from the workbook.
- Status written back into a column for each row so you can confirm completion at a glance.
- Any row that fails (contact ID not found, invalid format) gets an error note instead of a silent skip.
- 200 records updated without a single manual navigation session in sevdesk.
What If the Data Is Not Quite Ready
Column B and C contain full name split into first and last — plus email in D and phone in E
For each row in my Contact Corrections worksheet, update the sevdesk contact in column A — set first name to column B, last name to column C, email to column D, and phone to column E — write 'updated' in column F on success
Some email cells in column D are blank — update only the phone for those rows
For each row in my Contact Corrections worksheet, update the sevdesk contact in column A — if column D is not empty, update the email; always update the phone to column E — write 'updated' in column F on success, skip the email update where column D is blank
The corrections are split across two worksheets — Enterprise and SMB — same column layout
Update sevdesk contacts from both the Enterprise worksheet and the SMB worksheet — in both cases column A is the contact ID, column C is the new email, column D is the new phone — write 'updated' in column E on each worksheet after each successful update
Full cleanup pipeline: validate emails, update, and summarize
In my Contact Corrections worksheet: first scan column C — flag any malformed email (no @ or no domain) with INVALID in column E — then for rows where column E is still blank, update the sevdesk contact in column A with the email in column C and phone in column D — write 'updated' in column E for successes — write the total number of updates completed into cell A1
The validation catches the bad emails before they get pushed to sevdesk, saving you the cleanup of rejections mid-run.
Try It
Get the 7-day free trial of SheetXAI and open the Excel workbook with your corrected contact data, then ask it to push every change into sevdesk. When the contacts are updated, you can set custom field values like industry or segment on the same records, or bulk-import any new contacts that haven't been created yet.
