You will get I will fix Japanese mojibake: characters not showing in Excel and CSV

Project details
Your file shows strings like æååã where Japanese text should be. The data is almost never lost. It is being decoded with the wrong character encoding, and that can be reversed.
Most files that reach me are Shift-JIS or CP932 being read as UTF-8, or a UTF-8 file opened by Excel on Windows, which assumes Shift-JIS for CSV unless the file carries a byte order mark. I check the actual bytes instead of guessing, tell you which case it is, and convert the file to the encoding your program expects.
Then I read the Japanese. This is the part a converter cannot do. A file can come back looking repaired while containing characters that are not real words, and only someone who reads Japanese will notice. I check the text and flag anything ambiguous rather than guessing at it.
I also fix what tends to break once the encoding is sorted out: full-width numbers and letters are converted to half-width so sorting, lookups and totals behave, and Japanese era dates such as Reiwa 6 become real date values.
You get the corrected file, plus a short note explaining what the original encoding was, so you can stop it happening at the source.

About Keiji
Japan research, JA-EN translation, and document-to-data work
Tokyo, Japan - 4:07 pm local time
Three areas:
Research on the Japanese market. I read the original Japanese material — company filings, price pages, government statistics, industry reports, what customers write in reviews and Q&A threads — and write it up in English with every source listed, dated, and marked as official or estimated. Anything I could not confirm stays blank and labelled, because a report you cannot audit is a report you cannot use.
Japanese to English translation. Japanese sentence structure does not survive direct translation. I rebuild for an English reader, then run the result through the same mechanical checks I use on original English writing: repeated sentence openings, uniform sentence length, worn-out phrasing. Output that came straight from a model fails those checks nearly every time.
Turning documents into data. Tables locked in PDFs and scans, extracted into Excel or CSV, with unclear cells flagged rather than guessed.
How I work: in writing. I do not take calls or video meetings, and I answer messages the same day. If a request needs a live conversation, I am the wrong choice and will say so early.
What I will not do: invent experience I do not have, write a review of something I have not used, or fill a gap in a report with a plausible-sounding number.
Steps for completing your project
After purchasing the project, send requirements so Keiji can start the project.
Delivery time starts when Keiji receives requirements from you.
Keiji works on your project following the steps below.
Revisions may occur after the delivery date.
Identify what the encoding actually is
Garbled Japanese has a specific cause. I check the bytes rather than guessing, and tell you which encoding the file really is, so you know why it happened.
Convert it and read the result
I convert to the encoding your program expects, then read the Japanese to confirm the characters came back correctly. A converter cannot check this. A reader can.
