Will this work with Excel files exported from tools like Salesforce or HubSpot?

Yes. Any .xlsx or .xls file is supported regardless of its source. Headers exported from CRMs or ERPs often contain mixed case and spaces, which this tool corrects.

Does the tool preserve sheet names and row counts?

Sheet names are preserved. Row counts are unchanged — only the first row (headers) of each sheet is modified.

Can I normalize headers as part of a repeatable file intake process?

Yes. Deliteful is web-based, so any team member can normalize a file before passing it to the next step in your workflow — no script setup required.

What does snake_case mean for column headers?

Snake_case means all lowercase letters with words separated by underscores — for example, 'Invoice Date' becomes 'invoice_date'. This format is standard in databases, APIs, and most programming languages.

Stop Manually Fixing Headers Before Every Spreadsheet Automation Run

Spreadsheet automations built on Power Automate, Zapier, or custom scripts fail silently when an upstream Excel file arrives with a header that's shifted by one space or changed to title case. Normalizing headers to a predictable snake_case format before automation removes the single most common cause of schema-mismatch failures.

Automation workflows that consume Excel files are brittle by default because they depend on exact column name matches. When the source file is generated by a human — or by a third-party export — headers change unpredictably. 'Invoice Date' becomes 'Invoice date' becomes 'invoice-date'. Each variation silently breaks the field mapping downstream. A normalization step at file intake makes the automation robust to upstream formatting variation.

Deliteful's Excel Normalize Headers tool applies a deterministic transformation: lowercase, trim, replace spaces and hyphens with underscores. The output is a file your automation can consume reliably, regardless of how the source headers were typed. Processing costs 1 credit per file — light enough to include in any routine file intake workflow.

How it works

1
Upload the Excel file from your automation source

2
Normalize headers
Deliteful converts all headers across all sheets to lowercase snake_case automatically.
3
Feed the normalized file to your automation
Download and use the cleaned file as the reliable input your workflow expects.
