Easily Convert EML to Excel Spreadsheets Without Data Loss

“Have hundreds of EML files from Thunderbird that need to be in Excel for our quarterly audit. Tried opening them manually, but formatting breaks every single time. Need a reliable way to convert EML files along with attachments without losing anything important.”

EML files stored outside Excel are not just inconvenient for businesses, it is a genuine operational risk. Audit trails, compliance records, and client correspondence locked inside individual EML files serve no one when reporting deadlines hit. Excel is where data gets analyzed, filtered, and acted on, as EML is not built for any of that. To convert EML to Excel properly, the process needs to pull every metadata field, preserve attachments, and handle bulk files. This blog covers two free manual routes and the SysInfo EML Converter for a complete and accurate conversion.

What Are the Free Ways to Convert EML File to Excel?

Neither route below turns an EML file into an XLSX file with a single click. Each one needs a few extra steps to move the data from one format to another. One path goes through Outlook first, and the other relies on Excel’s built‑in object or import options to bring the EML data in. Go through both carefully before attempting either one on business-critical data.

Route 1: Convert EML to XLSX via Outlook Save As TXT

This route uses Microsoft Outlook as a bridge between the EML file and Excel. It works for individual files and requires both Outlook and Excel installed on the same system:

  1. Open Microsoft Outlook on your system and find the EML file you want to work with.
  2. Then double‑click that EML file so it opens inside Outlook like a normal email.
  3. Once it loads, go to the File menu and pick Save As from the options.
  4. Next, set the file type to Text Only (.txt) and save it in a folder you can remember.
  5. After that, move over to Microsoft Excel and launch it on the same PC.
  6. In Excel, click File > Open and change the bottom dropdown to All Files so you can see your TXT file.
  7. Next, browse to the folder where you saved the TXT file, pick it, and double‑click to open it.
  8. From there, the Text Import Wizard will pop up, and you can use commas or other separators to split the data.
  9. Take a quick look and adjust the columns so the data matches how you plan to use it.
  10. Finally, click File > Save As, pick XLSX from the format list, and save the file to finish the EML‑to‑Excel conversion.

Verify the output file opens correctly in Excel and check that all visible fields are transferred accurately.

This wraps up Route 1 to convert EML files to Excel through Outlook’s Save As feature. That said, this route has real limitations that become obvious the moment volume or data precision matters. 

Route 2: Convert EML To Excel Using Insert Object

This route uses Excel’s built‑in Insert Object feature to drop EML content straight into the sheet. No Outlook configuration is needed here, just Excel and the EML file sitting on your system:

  1. First, open Microsoft Excel and create a new blank workbook to start fresh.
  2. Next, click the Insert tab from the top menu ribbon inside Excel.
  3. After that, select Object from the Text group on the right side of the ribbon.
  4. Then, in the Object dialog box, click Create from File to switch to file selection mode.
  5. Click the Browse button and go to the folder where your EML file is saved on the computer.
  6. Pick the specific EML file you want, then press OK so it shows up as an embedded object right inside your Excel sheet.
  7. When that’s done, head to File > Save As, choose XLSX from the format list, and save the workbook to finish the step.

Reopen your XLSX file to verify the EML content shows up correctly. With that, Route 2 using Insert Object is complete. These tricks suit simple, manual tasks, not large or repeated workflows.

What Goes Wrong With These Manual Routes?

  • Route 1 only handles one EML at a time, so hundreds of emails become a slow, tedious job.
  • Route 2 just drops the EML into Excel as an object, not as clean columns anybody can work with.
  • Fields like CC, BCC, and attachment details often get lost or turn into empty cells.
  • HTML formatting in the email body turns into messy, hard‑to‑read text once it hits Excel.
  • Attachments stay locked inside the EML and never unpack into the workbook on their own.
  • Every file needs someone to click through the steps, which is not suitable for large‑scale use.

Is There a Faster Way to Convert EML to Excel in Bulk?

Manual approaches may work for small-scale files, but when dealing with enterprise-level data, you need SysInfo EML Converter Software. The utility converts every EML file with precision and extracts all metadata fields directly into structured Excel columns. Bulk conversion runs without size restrictions, and every field lands exactly where it belongs inside the XLSX output. It preserves your folder structure and allows users to convert EML to MBOX and other formats.

Real Case Scenario 

A UK financial firm nearly missed its audit deadline as its files were locked in EML format. Manual EML‑to‑Excel routes broke formatting and lost attachments. They used the SysInfo EML Converter Tool on all 400 files in one go. Every field landed in clean Excel columns with no data loss and intact folder structure. The audit workbook was ready the same day.

EML files and Excel rarely play well together without the right converter between them.

The SysInfo EML Converter Tool handles this properly, turning every field, attachment, and metadata value into clean, structured XLSX files in one go. It is built for teams that need reliable, audit‑ready EML‑to‑Excel conversion at scale.
