Upload shows a file type error — how do I fix it?

Last updated on Aug 31, 2026

Short Answer: Make sure your file is one of the supported types shown under the upload area: CSV, XLS, or XLSX, then re-upload.

PreRequisites

  1. Have the source data file available on your computer

Steps

  1. Check the file extension of the file you tried to upload.
    You can confirm whether the file ends with .csv, .xls or .xlsx.

  2. If the file is a different type, export or save it from your source system as CSV, XLS, or XLSX.
    A new file in a supported format is available.

  3. Retry clicking the "Upload file" area and select the converted file.
    The upload succeeds without the file type error.

  4. If the problem persists, try a different browser or check network stability.
    Upload succeeds or you capture a clearer error to report to support.

Troubleshooting

  1. File still rejected after conversion.
    LikelyCause: File may be corrupted or contain unsupported internal format/content.
    Action: Open the file in Excel or similar and resave; simplify the file by removing macros/unsupported objects and retry.

  2. Upload completes but reconciliation fails later.
    LikelyCause: File content or column layout may not match reconciliation expectations.
    Action: Check file contents and headers; consult your reconciliation template or support for required columns.

Note: Supported file types are shown in the upload area as "CSV, XLS, XLSX".
