MX Batch File Checker (Beta) Version: 2025.11.24

Welcome! This tool helps you check MX Batch CSV files before sending them.

Note: All processing happens locally in your browser. No data is uploaded to MX or elsewhere.

• Steps
1. Choose Files and Check Them. Select the relevant CSV files from your computer: 1 Manifest, User, Member, Account, and/or Transaction (the Manifest must be included); and select the "Validate Files" button.
• The tool will check filenames, SHA256 checksums, and validate data against the MX Batch file specification.
• For uploading multiple files of the same type in the same batch on the same day, see this section of the MX documentation.
• Limitation: Parent object checks (e.g., an Account's `user_id`) only check against other records in this batch. It cannot check for IDs that already exist at MX.
2. Review Results:
• Green Text = Proceed with submitting those Batch files to MX
• Red Text = Make the noted changes to the files and re-check
Continue making the necessary changes to your Batch files until you receive the green text message, "Validation Complete. All checks passed!" before submitting those files. Remember to submit the Batch files to MX.

Note: This is a beta tool. There may be unintended discrepancies with the results. Please contact your MX Relationship Management Representative with questions.
